K. Dewhurst, S. Sharma and L. Nordstr\"{o}m} ! !AFFILIATION: ! !INTRODUCTION: Introduction ! Spacegroup is a utility which produces crystal geometry for use with the Elk ! code, from the space group defined by its Hermann-Mauguin symbol and lattice ! vector lengths and angles. Spacegroup recognises all 230 space groups in ! various coordinate settings giving a total of 530 possible symbols, which are ! tabulated below. The code also provides output compatible with the XCrysDen or ! V\_Sim packages for visualisation of the crystal structure. ! \section{Usage} ! Only one input file, {\tt spacegroup.in}, is required. The structure of this ! file is illustrated by the following example for the high $T_c$ superconductor ! La$_2$CuO$_4$: ! \begin{verbatim} !

The Hermann-Mauguin symbol of a space group listed in the table below. ! (case-sensitive) ! \vskip 6pt ! {\tt a}, {\tt b}, {\tt c}\\ ! Lattice vector lengths in Bohr (i.e. atomic units, {\bf NOT} \AA ngstroms). ! \vskip 6pt ! {\tt bc}, {\tt ac}, {\tt ab}\\ ! Angles in degrees between lattice vectors ${\bf b}$ and ${\bf c}$ ($\alpha$); ! ${\bf a}$ and ${\bf c}$ ($\beta$); and ${\bf a}$ and ${\bf b}$ ($\gamma$). ! \vskip 6pt ! {\tt ncell}\\ ! The number of unit cells required in each direction. ! \vskip 6pt ! {\tt primcell}\\ ! Set to {\tt .true.} if the primitive unit cell should be found. ! \vskip 6pt ! {\tt nspecies}\\ ! Number of atomic species. ! \vskip 6pt ! {\tt spsymb}\\ ! The atomic species symbol. ! \vskip 6pt ! {\tt nwpos}\\ ! The number of Wyckoff positional coordinates. ! \vskip 6pt ! {\tt wpos}\\ ! Wyckoff positional coordinates in fractions of the lattice vectors. ! \vskip 6pt ! Note that {\tt nwpos} and {\tt wpos} are repeated as many times as there are ! species. After creating the input file, the {\tt spacegroup} command is run ! and the files {\tt GEOMETRY.OUT} and {\tt crystal.xsf} should be produced. ! The {\tt GEOMETRY.OUT} file can simply be appended to an {\tt elk.in} file. If ! XCrysDen is available, then use the command ! \vskip 6pt ! \hskip 24pt {\tt xcrysden --xsf crystal.xsf} ! \vskip 6pt ! to render the unit cell. ! \section{Table of space group symbols} !

Elk is an all-electron full-potential linearised ! augmented-plane-wave (FP-LAPW) code for determining the properties of ! crystalline solids. It was developed originally at the ! Karl-Franzens-Universit\"{a}t Graz as part of the EXCITING EU Research and ! Training Network project\footnote{EXCITING code developed under the Research ! and Training Network EXCITING funded by the EU, contract No. ! HPRN-CT-2002-00317}. The guiding philosophy during the implementation of the ! code was to keep it as simple as possible for both users and developers ! without compromising on its capabilities. All the routines are released ! under either the GNU General Public License (GPL) or the GNU Lesser General ! Public License (LGPL) in the hope that they may inspire other scientists to ! implement new developments in the field of density functional theory and ! beyond. ! ! \section{Acknowledgments} !

Unless explicitly stated otherwise, Elk uses atomic units. In this system ! $\hbar=1$, the electron mass $m=1$, the Bohr radius $a_0=1$ and the electron ! charge $e=1$ (note that the electron charge is positive, so that the atomic ! numbers $Z$ are negative). Thus the atomic unit of length is ! 0.529177210903(80) \AA, and the atomic unit of energy is the Hartree which ! equals 27.211386245988(53) eV. The unit of the external magnetic fields is ! defined such that one unit of magnetic field in {\tt elk.in} equals ! 1715.255541 Tesla. ! ! \section{Compiling and running Elk} ! \subsection{Compiling the code} ! Unpack the code from the archive file. Edit the file {\tt make.inc} in the ! {\tt elk} directory and adjust the compiler options for your computer ! system. Use of machine-optimised BLAS/LAPACK and FFT libraries will result ! in significant increase in performance. Following this, run ! \begin{verbatim} ! make ! \end{verbatim} ! This will hopefully compile the entire code and all the libraries into one ! executable, {\tt elk}, located in the {\tt elk/src} directory. It will also ! compile two useful auxiliary programs, namely {\tt spacegroup} for producing ! crystal geometries from spacegroup data and {\tt eos} for fitting equations ! of state to energy-volume data. If you want to compile everything all over ! again, then run {\tt make clean} from the {\tt elk} directory, followed by ! {\tt make}. ! \subsubsection{Parallelism in Elk} ! Three forms of parallelism are implemented in Elk, and all can be used in ! combination with each other, with efficiency depending on the particular ! task, crystal structure and computer system. You may need to contact your ! system administrator for assistance with running Elk in parallel. ! \begin{enumerate} ! \item ! OpenMP works for symmetric multiprocessors, i.e. computers that have many ! cores with the same unified memory accessible to each. It is enabled by ! setting the appropriate command-line options (e.g. {\tt -qopenmp} for the ! Intel compiler) before compiling, and also at runtime by the environment ! variable ! \begin{verbatim} ! export OMP_NUM_THREADS=n ! \end{verbatim} ! where n is the number of cores available on a particular node. The same can ! be accomplished in {\tt elk.in} with ! \begin{verbatim} ! maxthd ! n ! \end{verbatim} ! In addition, some vendor-supplied BLAS/LAPACK libraries use OpenMP ! internally. The maximum number of threads used for LAPACK operations by ! Intel's MKL can be set with ! \begin{verbatim} ! maxthdmkl ! n ! \end{verbatim} ! \item ! The message passing interface (MPI) is particularly suitable for running ! Elk across multiple nodes of a cluster, with scaling to hundreds of ! processors possible. To enable MPI, comment out the lines indicated in ! {\tt elk/make.inc}. Then run {\tt make clean} followed by {\tt make}. If ! $y$ is the number of nodes and $x$ is the number of cores per node, then at ! runtime envoke ! \begin{verbatim} ! mpirun -np z ./elk ! \end{verbatim} ! where $z=x y$ is the total number of cores available on the machine. ! Highest efficiency is obtained by using hybrid parallelism with OpenMP on ! each node and MPI across nodes. This can be done by compiling the code ! using the MPI Fortran compiler in combination with the OpenMP command-line ! option. At runtime set {\tt export OMP\_NUM\_THREADS=x} and start the MPI ! run with {\em one process per node} as follows ! \begin{verbatim} ! mpirun -pernode -np y ./elk ! \end{verbatim} ! The number of MPI processes is reported in the file {\tt INFO.OUT} which ! serves as a check that MPI is running correctly. Note that version 2 of the ! MPI libraries is required to run Elk. ! \item ! Phonon calculations use a simple form of parallelism by just examining the ! run directory for dynamical matrix files. These files are of the form ! \begin{verbatim} ! DYN_Qqqqq_qqqq_qqqq_Sss_Aaa_Pp.OUT ! \end{verbatim} ! and contain a single row of a particular dynamical matrix. Elk simply finds ! which {\tt DYN} files do not exist, chooses one and runs it. This way many ! independent runs of Elk can be started in the same directory on a networked ! file system (NFS), and will run until all the dynamical matrices files are ! completed. Should a particular run crash, then delete the associated empty ! {\tt DYN} file and rerun Elk. ! \end{enumerate} ! ! \subsection{Memory requirements} ! Elk is a memory-bound code and runs best on processors with large caches and ! a large number of memory channels per core. Some tasks in Elk require a ! considerable amount of memory which can exceed the physical memory of the ! computer. In such cases, the number of threads at the first nesting level ! can be reduced with (for example) ! \begin{verbatim} ! maxthd1 ! -4 ! \end{verbatim} ! which restricts the number of threads at the first nesting level to ! maxthd/4. Deeper nesting levels, which generally require less memory, will ! still utilise the full compliment of available threads. ! \subsubsection{Stack space} ! The latest versions of Elk use stack space aggressively. This is because ! accessing variables is faster on the stack than on the heap. This can, ! however, result in the code crashing as threads run out of their stack ! space. To avoid this, increase the stack size for each OpenMP thread with ! (for example) ! \begin{verbatim} ! export OMP_STACKSIZE=512M ! \end{verbatim} ! before running the code. ! ! \subsection{Linking with the Libxc functional library} ! Libxc is a library of exchange-correlation functionals. Elk can use the ! complete set of LDA and GGA functionals available in Libxc as well as some ! meta-GGAs. In order to enable this, first download and compile Libxc. This ! should have produced the files {\tt libxc.a} and {\tt libxcf03.a} in the ! Libxc directory {\tt src/.libs}. Copy these to the {\tt elk/src} directory ! and then uncomment the lines indicated for Libxc in {\tt elk/make.inc}. Once ! this is done, run {\tt make clean} followed by {\tt make}. To select a ! particular functional of Libxc, use the block ! \begin{verbatim} ! xctype ! 100 nx nc ! \end{verbatim} ! where {\tt nx} and {\tt nc} are, respectively, the numbers of the exchange ! and correlation functionals in the Libxc library. See the file ! {\tt elk/src/libxcf03.f90} for a list of the functionals and their ! associated numbers. ! ! \subsection{Running the code} ! As a rule, all input files for the code are in lower case and end with the ! extension {\tt .in}. All output files are uppercase and have the extension ! {\tt .OUT}. For most cases, the user will only need to modify the file ! {\tt elk.in}. In this file input parameters are arranged in blocks. ! Each block consists of a block name on one line and the block variables on ! subsequent lines. Almost all blocks are optional: the code uses reasonable ! default values in cases where they are absent. Blocks can appear in any ! order, if a block is repeated then the second instance is used. Comment ! lines can be included in the input file and begin with the {\tt !} ! character. ! ! \subsubsection{Species files} ! The only other input files are those describing the atomic species which go ! into the crystal. These files are found in the {\tt species} directory and ! are named with the element symbol and the extension {\tt .in}, for example ! {\tt Sb.in}. They contain parameters like the atomic charge, mass, ! muffin-tin radius, occupied atomic states and the type of linearisation ! required. Here as an example is the copper species file {\tt Cu.in}: ! \begin{verbatim} ! 'Cu' : spsymb ! 'copper' : spname ! -29.0000 : spzn ! 115837.2716 : spmass ! 0.371391E-06 2.0000 34.8965 500 : rminsp, rmt, rmaxsp, nrmt ! 10 : nstsp ! 1 0 1 2.00000 T : nsp, lsp, ksp, occsp, spcore ! 2 0 1 2.00000 T ! 2 1 1 2.00000 T ! 2 1 2 4.00000 T ! 3 0 1 2.00000 T ! 3 1 1 2.00000 F ! 3 1 2 4.00000 F ! 3 2 2 4.00000 F ! 3 2 3 6.00000 F ! 4 0 1 1.00000 F ! 1 : apword ! 0.1500 0 F : apwe0, apwdm, apwve ! 1 : nlx ! 2 2 : lx, apword ! 0.1500 0 T : apwe0, apwdm, apwve ! 0.1500 1 T ! 4 : nlorb ! 0 2 : lorbl, lorbord ! 0.1500 0 F : lorbe0, lorbdm, lorbve ! 0.1500 1 F ! 1 2 ! 0.1500 0 F ! 0.1500 1 F ! 2 2 ! 0.1500 0 F ! 0.1500 1 F ! 1 3 ! 0.1500 0 F ! 0.1500 1 F ! -2.8652 0 T ! \end{verbatim} ! The input parameters are defined as follows: ! \vskip 6pt ! {\tt spsymb} \\ ! The symbol of the element. ! \vskip 6pt ! {\tt spname} \\ ! The name of the element. ! \vskip 6pt ! {\tt spzn} \\ ! Nuclear charge: should be negative since the electron charge is taken to be ! postive in the code; it can also be fractional for purposes of doping. ! \vskip 6pt ! {\tt spmass} \\ ! Nuclear mass in atomic units. ! \vskip 6pt ! {\tt rminsp}, {\tt rmt}, {\tt rmaxsp}, {\tt nrmt} \\ ! Respectively, the minimum radius on logarithmic radial mesh; muffin-tin ! radius; effective infinity for atomic radial mesh; and number of radial mesh ! points to muffin-tin radius. ! \vskip 6pt ! {\tt nstsp} \\ ! Number of atomic states. ! \vskip 6pt ! {\tt nsp}, {\tt lsp}, {\tt ksp}, {\tt occsp}, {\tt spcore} \\ ! Respectively, the principal quantum number of the radial Dirac equation; ! quantum number $l$; quantum number $k$ ($l$ or $l+1$); occupancy of atomic ! state (can be fractional); {\tt .T.} if state is in the core and therefore ! treated with the Dirac equation in the spherical part of the muffin-tin ! Kohn-Sham potential. ! \vskip 6pt ! {\tt apword} \\ ! Default APW function order, i.e. the number of radial functions and ! therefore the order of the radial derivative matching at the muffin-tin ! surface. ! \vskip 6pt ! {\tt apwe0}, {\tt apwdm}, {\tt apwve} \\ ! Respectively, the default APW linearisation energy; the order of the energy ! derivative of the APW radial function $\partial^m u(r)/\partial E^m$; and ! {\tt .T.} if the linearisation energy is allowed to vary. ! \vskip 6pt ! {\tt nlx} \\ ! The number of exceptions to the default APW configuration. These should be ! listed on subsequent lines for particular angular momenta. In this example, ! the fixed energy APW with angular momentum $d$ ({\tt lx} $=2$) is replaced ! with a LAPW, which has variable linearisation energy. ! \vskip 6pt ! {\tt nlorb} \\ ! Number of local-orbitals. ! \vskip 6pt ! {\tt lorbl}, {\tt lorbord} \\ ! Respectively, the angular momentum $l$ of the local-orbital; and the order ! of the radial derivative which goes to zero at the muffin-tin surface. ! \vskip 6pt ! {\tt lorbe0}, {\tt lorbdm}, {\tt lorbve} \\ ! Respectively, the default local-orbital linearisation energy; the order of ! the energy derivative of the local-orbital radial function; and {\tt .T.} if ! the linearisation energy is allowed to vary. ! ! \subsubsection{Examples} ! The best way to learn to use Elk is to run the examples included with the ! package. These can be found in the {\tt examples} directory and use many of ! the code's capabilities. The following section which describes all the input ! parameters will be of invaluable assistance. ! ! \section{Input blocks} ! This section lists all the input blocks available. It is arranged with the ! name of the block followed by a table which lists each parameter name, what ! the parameter does, its type and default value. A horizontal line in the ! table indicates a new line in {\tt elk.in}. Below the table is a brief ! overview of the block's function. ! ! \block{atoms}{ ! {\tt nspecies} & number of species & integer & 0 \\ ! \hline ! {\tt spfname(i)} & species filename for species $i$ & string & - \\ ! \hline ! {\tt natoms(i)} & number of atoms for species $i$ & integer & - \\ ! \hline ! {\tt atposl(j,i)} & atomic position in lattice coordinates for atom $j$ ! & real(3) & - \\ ! {\tt bfcmt(j,i)} & muffin-tin external magnetic field in Cartesian ! coordinates for atom $j$ & real(3) & -} ! Defines the atomic species as well as their positions in the unit cell and ! the external magnetic field applied throughout the muffin-tin. These fields ! are used to break spin symmetry and should be considered infinitesimal as ! they do not contribute directly to the total energy. Collinear calculations ! are more efficient if the field is applied in the $z$-direction. One could, ! for example, set up an antiferromagnetic crystal by pointing the field on ! one atom in the positive $z$-direction and in the opposite direction on ! another atom. If {\tt molecule} is {\tt .true.} then the atomic positions ! are assumed to be in Cartesian coordinates.

See {\tt dlefe} for details. ! ! \block{autoswidth}{ ! {\tt autoswidth} & {\tt .true.} if the smearing parameter {\tt swidth} ! should be determined automatically & logical & {\tt .false.}} ! Calculates the smearing width from the $k$-point density, $V_{\rm BZ}/n_k$; ! the valence band width, $W$; and an effective mass parameter, $m^{*}$; ! according to ! $$ \sigma=\frac{\sqrt{2W}}{m^{*}}\left(\frac{3}{4\pi} ! \frac{V_{\rm BZ}}{n_k}\right)^{1/3}. $$ ! The variable {\tt mstar} then replaces {\tt swidth} as the control parameter ! of the smearing width. A large value of $m^{*}$ gives a narrower smearing ! function. Since {\tt swidth} is adjusted according to the fineness of the ! ${\bf k}$-mesh, the smearing parameter can then be eliminated. It is not ! recommended that {\tt autoswidth} be used in conjunction with the ! Fermi-Dirac smearing function, since the electronic temperature will then be ! a function of the $k$-point mesh. See T. Bj\"orkman and O. Gr\aa n\"as, ! {\it Int. J. Quant. Chem.} DOI: 10.1002/qua.22476 (2010) for details.

These are then transformed to be identical to those ! calculated with {\tt avec}. The purpose of this is to enable accurate ! energy-volume curves, where the number of grid points should remain fixed ! for all volumes. ! ! \block{beta0}{ ! {\tt beta0} & adaptive mixing parameter & real & $0.05$} !

Maximum allowed mixing parameter used in routine {\tt mixadapt}. ! ! \block{bfieldc}{ ! {\tt bfieldc} & global external magnetic field in Cartesian coordinates & ! real(3) & $(0.0,0.0,0.0)$} ! This is a constant magnetic field applied throughout the entire unit cell ! and enters the second-variational Hamiltonian as ! $$ \frac{g_e}{4c}\,\vec{\sigma}\cdot{\bf B}_{\rm ext}, $$ ! where $g_e$ is the electron $g$-factor. This field is normally used to break ! spin symmetry for spin-polarised calculations and considered to be ! infinitesimal with no direct contribution to the total energy. In cases ! where the magnetic field is finite (for example when computing magnetic ! response) the external ${\bf B}$-field energy reported in {\tt INFO.OUT} ! should be added to the total by hand. This field is applied throughout the ! entire unit cell. To apply magnetic fields in particular muffin-tins use the ! {\tt bfcmt} vectors in the {\tt atoms} block.

This variable can be set to .true. in cases where the magnetism is ! predominantly collinear in the $z$-direction, for example a ferromagnet with ! spin-orbit coupling.

Phonon calculations are performed by constructing a supercell corresponding ! to a particular ${\bf q}$-vector and making a small periodic displacement of ! the atoms. The magnitude of this displacement is given by {\tt deltaph}. ! This should not be made too large, as anharmonic terms could then become ! significant, neither should it be too small as this can introduce numerical ! error. ! ! \block{deltast}{ ! {\tt deltast} & size of the change in lattice vectors used for calculating ! the stress tensor & real & $0.005$} ! The stress tensor is computed by changing the lattice vector matrix $A$ by ! $$ A\rightarrow (1+\delta t\,e_k)A, $$ ! where $\delta t$ is an infinitesimal equal in practice to {\tt deltast} and ! $e_k$ is the $k^{\rm th}$ strain tensor.

Please bear in mind when writing code for the Elk project that it should be ! an exercise in physics and not software engineering. All code should ! therefore be kept as simple and concise as possible, and above all it should ! be easy for anyone to locate and follow the Fortran representation of the ! original mathematics. We would also appreciate the following conventions ! being adhered to: ! \begin{itemize} ! \item Strict Fortran 2008 should be used. Features which are marked as ! obsolescent in Fortran 2008 should be avoided. These include assigned ! format specifiers, labeled do-loops, computed goto statements and statement ! functions. ! \item Modules should be used in place of common blocks for declaring ! global variables. Use the existing modules to declare new global variables. ! \item Any code should be written in lower-case free form style, starting ! from column one. Try and keep the length of each line to fewer than 80 ! characters using the \& character for line continuation. ! \item Every function or subroutine, no matter how small, should be in its ! own file named {\tt routine.f90}, where {\tt routine} is the function or ! subroutine name. It is recommended that the routines are named so as to ! make their purpose apparent from the name alone. ! \item Use of {\tt implicit none} is mandatory. Remember also to define the ! {\tt intent} of any passed arguments. ! \item Local allocatable arrays must be deallocated on exit of the routine to ! prevent memory leakage. Use of automatic arrays should be limited to arrays ! of small size. ! \item Every function or subroutine must be documented with the Protex source ! code documentation system. This should include a short \LaTeX\ description ! of the algorithms and methods involved. Equations which need to be ! referenced should be labeled with {\tt routine\_1}, {\tt routine\_2}, etc. ! The authorship of each new piece of code or modification should be ! indicated in the {\tt REVISION HISTORY} part of the header. See the Protex ! documentation for details. ! \item Ensure as much as possible that a routine will terminate the program ! when given improper input instead of continuing with erroneous results. ! Specifically, functions should have a well-defined domain for which they ! return accurate results. Input outside that domain should result in an ! error message and termination. ! \item Report errors prior to termination with a short description, for ! example: ! \begin{verbatim} ! write(*,*) ! write(*,'("Error(readinput): natoms < 1 : ",I8)') natoms(is) ! write(*,'(" for species ",I4)') is ! write(*,*) ! stop ! \end{verbatim} ! \item Wherever possible, real numbers outputted as ASCII data should be ! formatted with the {\tt G18.10} specifier. ! \item Avoid redundant or repeated code: check to see if the routine you need ! already exists, before writing a new one. ! \item All reading in of ASCII data should be done in the subroutine ! {\tt readinput}. For binary data, separate routines for reading and writing ! should be used (for example {\tt writestate} and {\tt readstate}). ! \item Input filenames should be in lowercase and have the extension ! {\tt .in} . All output filenames should be in uppercase with the extension ! {\tt .OUT} . ! \item All internal units should be atomic. Input and output units should be ! atomic by default and clearly stated otherwise. Rydbergs should not be used ! under any circumstances. ! \end{itemize} ! \subsection{Licensing} ! Routines which constitute the main part of the code are released under the ! GNU General Public License (GPL). Library routines are released under the ! less restrictive GNU Lesser General Public License (LGPL). Both licenses ! are contained in the file {\tt COPYING}. Any contribution to the code must ! be licensed at the authors' discretion under either the GPL or LGPL. ! Author(s) of the code retain the copyrights. Copyright and (L)GPL ! information must be included at the beginning of every file, and no code ! will be accepted without this. ! !EOI elk-10.4.9/src/PaxHeaders/energynn.f900000644000000000000000000000013214762655564014416 xustar0030 mtime=1741380468.498008617 30 atime=1741380466.520998281 30 ctime=1741380468.498008617 elk-10.4.9/src/energynn.f900000644002504400250440000000230214762655564017135 0ustar00dewhurstdewhurst00000000000000 !

Computes the various contributions to the atomic forces. In principle, the ! force acting on a nucleus is simply the gradient at that site of the ! classical electrostatic potential from the other nuclei and the electronic ! density. This is a result of the Hellmann-Feynman theorem. However because ! the basis set is dependent on the nuclear coordinates and is not complete, ! the Hellman-Feynman force is inaccurate and corrections to it are required. ! The first is the core correction which arises because the core wavefunctions ! were determined by neglecting the non-spherical parts of the Kohn-Sham ! potential $v_s$. Explicitly this is given by ! $$ {\bf F}_{\rm core}^{\alpha}=\int_{\rm MT_{\alpha}} v_s({\bf r}) ! \nabla\rho_{\rm core}^{\alpha}({\bf r})\,d{\bf r} $$ ! for atom $\alpha$. The second, which is the incomplete basis set (IBS) ! correction, is due to the position dependence of the APW functions, and is ! derived by considering the change in total energy if the eigenvector ! coefficients were fixed and the APW functions themselves were changed. This ! would result in changes to the first-variational Hamiltonian and overlap ! matrices given by ! \begin{align*} ! \delta H_{\bf G,G'}^{\alpha}&=i({\bf G-G'}) ! \left(H^{\alpha}_{\bf G+k,G'+k}-\frac{1}{2}({\bf G+k})\cdot({\bf G'+k}) ! \tilde{\Theta}_{\alpha}({\bf G-G'})e^{-i({\bf G-G'})\cdot{\bf r}_{\alpha}} ! \right)\\ ! \delta O_{\bf G,G'}^{\alpha}&=i({\bf G-G'})\left(O^{\alpha}_{\bf G+k,G'+k} ! -\tilde{\Theta}_{\alpha}({\bf G-G'})e^{-i({\bf G-G'})\cdot{\bf r}_{\alpha}} ! \right) ! \end{align*} ! where both ${\bf G}$ and ${\bf G'}$ run over the APW indices; ! $\tilde{\Theta}_{\alpha}$ is the form factor of the smooth step function for ! muffin-tin $\alpha$; and $H^{\alpha}$ and $O^{\alpha}$ are the muffin-tin ! Hamiltonian and overlap matrices, respectively. The APW-local-orbital part ! is given by ! \begin{align*} ! \delta H_{\bf G,G'}^{\alpha}&=i({\bf G+k})H^{\alpha}_{\bf G+k,G'+k}\\ ! \delta O_{\bf G,G'}^{\alpha}&=i({\bf G+k})O^{\alpha}_{\bf G+k,G'+k} ! \end{align*} ! where ${\bf G}$ runs over the APW indices and ${\bf G'}$ runs over the ! local-orbital indices. There is no contribution from the ! local-orbital-local-orbital part of the matrices. We can now write the IBS ! correction in terms of the basis of first-variational states as ! \begin{align*} ! {\bf F}_{ij}^{\alpha{\bf k}}=\sum_{\bf G,G'} ! b^{i{\bf k}*}_{\bf G}b^{j{\bf k}}_{\bf G'}\left( ! \delta H_{\bf G,G'}^{\alpha}-\epsilon_j\delta O_{\bf G,G'}^{\alpha}\right), ! \end{align*} ! where $b^{i{\bf k}}$ is the first-variational eigenvector. ! Finally, the ${\bf F}_{ij}^{\alpha{\bf k}}$ matrix elements can be ! multiplied by the second-variational coefficients, and contracted over all ! indices to obtain the IBS force: ! \begin{align*} ! {\bf F}_{\rm IBS}^{\alpha}=\sum_{\bf k}w_{\bf k}\sum_{l\sigma}n_{l{\bf k}} ! \sum_{ij}c_{\sigma i}^{l{\bf k}*}c_{\sigma j}^{l{\bf k}} ! {\bf F}_{ij}^{\alpha{\bf k}} ! +\int_{\rm MT_{\alpha}}v_s({\bf r})\nabla\left[\rho({\bf r}) ! -\rho^{\alpha}_{\rm core}({\bf r})\right]\,d{\bf r}, ! \end{align*} ! where $c^{l{\bf k}}$ are the second-variational coefficients, $w_{\bf k}$ ! are the $k$-point weights, $n_{l{\bf k}}$ are the occupation numbers. ! ! !REVISION HISTORY: !

Given energy and weight functions, $e$ and $f$, on the Brillouin zone and a ! set of equidistant energies $\omega_i$, this routine computes the integrals ! $$ g(\omega_i)=\frac{\Omega}{(2\pi)^3}\int_{\rm BZ} f({\bf k}) ! \delta(\omega_i-e({\bf k}))d{\bf k}, $$ ! where $\Omega$ is the unit cell volume. This is done by first interpolating ! $e$ and $f$ on a finer $k$-point grid using the trilinear method. Then for ! each $e({\bf k})$ on the finer grid the nearest $\omega_i$ is found and ! $f({\bf k})$ is accumulated in $g(\omega_i)$. If the output function is ! noisy then either {\tt nsk} should be increased or {\tt nw} decreased. ! Alternatively, the output function can be artificially smoothed up to a ! level given by {\tt nsm}. See routine {\tt fsmooth}. ! ! !REVISION HISTORY: ! Created October 2003 (JKD) !

Computes the core radial wavefunctions, eigenvalues and densities. The ! radial Dirac equation is solved in the spherical part of the Kohn-Sham ! potential to which the atomic potential has been appended for ! $r>R_{\rm MT}$. In the case of spin-polarised calculations, and when ! {\tt spincore} is set to {\tt .true.}, the Dirac equation is solved in the ! spin-up and -down potentials created from the Kohn-Sham scalar potential and ! magnetic field magnitude, with the occupancy divided equally between up and ! down. The up and down densities determined in this way are added to both the ! scalar density and the magnetisation in the routine {\tt rhocore}. Note ! that this procedure is a simple, but inexact, approach to solving the radial ! Dirac equation in a magnetic field. ! ! !REVISION HISTORY: ! Created April 2003 (JKD) !

Computes the total energy and its individual contributions. The kinetic ! energy is given by ! $$ T_s=\sum_i n_i\epsilon_i-\int\rho({\bf r})[v_{\rm C}({\bf r}) ! +v_{\rm xc}({\bf r})]d{\bf r}-\int {\bf m}({\bf r})\cdot ! ({\bf B}_{\rm xc}({\bf r})+{\bf B}_{\rm ext}({\bf r}))d{\bf r}, $$ ! where $n_i$ are the occupation numbers and $\epsilon_i$ are the eigenvalues ! of both the core and valence states; $\rho$ is the density; ${\bf m}$ is the ! magnetisation density; $v_{\rm C}$ is the Coulomb potential; $v_{\rm xc}$ ! and ${\bf B}_{\rm xc}$ are the exchange-correlation potential and magnetic ! field, respectively; and ${\bf B}_{\rm ext}$ is the external magnetic field. ! The Hartree, electron-nuclear and nuclear-nuclear electrostatic energies are ! combined into the Coulomb energy: ! \begin{align*} ! E_{\rm C}&=E_{\rm H}+E_{\rm en}+E_{\rm nn} \\ ! &=\frac{1}{2}V_{\rm C}+E_{\rm Mad}, ! \end{align*} ! where ! $$ V_{\rm C}=\int\rho({\bf r})v_{\rm C}({\bf r})d{\bf r} $$ ! is the Coulomb potential energy. The Madelung energy is given by ! $$ E_{\rm Mad}=\frac{1}{2}\sum_{\alpha}z_{\alpha}R_{\alpha}, $$ ! where ! $$ R_{\alpha}=\lim_{r\rightarrow 0}\left(v^{\rm C}_{\alpha;00}(r)Y_{00} ! +\frac{z_{\alpha}}{r}\right) $$ ! for atom $\alpha$, with $v^{\rm C}_{\alpha;00}$ being the $l=0$ component of ! the spherical harmonic expansion of $v_{\rm C}$ in the muffin-tin, and ! $z_{\alpha}$ is the nuclear charge. Using the nuclear-nuclear energy ! determined at the start of the calculation, the electron-nuclear and Hartree ! energies can be isolated with ! $$ E_{\rm en}=2\left(E_{\rm Mad}-E_{\rm nn}\right) $$ ! and ! $$ E_{\rm H}=\frac{1}{2}(E_{\rm C}-E_{\rm en}). $$ ! Finally, the total energy is ! $$ E=T_s+E_{\rm C}+E_{\rm xc}, $$ ! where $E_{\rm xc}$ is obtained either by integrating the ! exchange-correlation energy density, or in the case of exact exchange, the ! explicit calculation of the Fock exchange integral. The energy from the ! external magnetic fields in the muffin-tins, {\tt bfcmt}, is always removed ! from the total since these fields are non-physical: their field lines do not ! close. The energy of the physical external field, {\tt bfieldc}, is also not ! included in the total because this field, like those in the muffin-tins, is ! used for breaking spin symmetry and taken to be infintesimal. If this field ! is intended to be finite, then the associated energy, {\tt engybext}, should ! be added to the total by hand. See {\tt potxc}, {\tt exxengy} and related ! subroutines. ! ! !REVISION HISTORY: !

The vector field can be the ! magnetisation vector field, ${\bf m}$; the exchange-correlation magnetic ! field, ${\bf B}_{\rm xc}$; or the electric field ! ${\bf E}\equiv-\nabla V_{\rm C}$. The magnetisation is obtained from the ! spin density matrix, $\rho_{\alpha\beta}$, by solving ! $$ \rho_{\alpha\beta}({\bf r})=\frac{1}{2}\left(n({\bf r}) ! \delta_{\alpha\beta}+\sigma\cdot {\bf m}({\bf r})\right), $$ ! where $n\equiv\tr\rho_{\alpha\beta}$ is the total density. In the case of 2D ! plots, the magnetisation vectors are still 3D, but are in the coordinate ! system of the plane. ! ! !REVISION HISTORY: ! Created August 2004 (JKD) !

Finds the complete set of symmetries which leave the crystal structure ! (including the magnetic fields) invariant. A crystal symmetry is of the form ! $\{\alpha_S|\alpha_R|{\bf t}\}$, where ${\bf t}$ is a translation vector, ! $\alpha_R$ is a spatial rotation operation and $\alpha_S$ is a global spin ! rotation. Note that the order of operations is important and defined to be ! from right to left, i.e. translation followed by spatial rotation followed ! by spin rotation. In the case of spin-orbit coupling $\alpha_S=\alpha_R$. In ! order to determine the translation vectors, the entire atomic basis is ! shifted so that the first atom in the smallest set of atoms of the same ! species is at the origin. Then all displacement vectors between atoms in ! this set are checked as possible symmetry translations. If the global ! variable {\tt tshift} is set to {\tt .false.} then the shift is not ! performed. See L. M. Sandratskii and P. G. Guletskii, {\it J. Phys. F: Met. !

Outputs the electron localisation function (ELF) for 1D, 2D or 3D plotting. ! The spin-averaged ELF is given by ! $$ f_{\rm ELF}({\bf r})=\frac{1}{1+[D({\bf r})/D^0({\bf r})]^2}, $$ ! where ! $$ D({\bf r})=\frac{1}{2}\left(\tau({\bf r})-\frac{1}{4} ! \frac{[\nabla n({\bf r})]^2}{n({\bf r})}\right) $$ ! and ! $$ \tau({\bf r})=\sum_{i=1}^N \left|\nabla\Psi_i({\bf r}) ! \right|^2 $$ ! is the spin-averaged kinetic energy density from the spinor wavefunctions. ! The function $D^0$ is the kinetic energy density for the homogeneous ! electron gas evaluated for $n({\bf r})$: ! $$ D^0({\bf r})=\frac{3}{5}(6\pi^2)^{2/3}\left(\frac{n({\bf r})}{2} ! \right)^{5/3}. $$ !

(inout,complex(ld3,*)) ! zvclir : interstitial Coulomb potential (out,complex(*)) ! !DESCRIPTION: ! Calculates the Coulomb potential of a complex charge density by solving ! Poisson's equation using the method of M. Weinert, {\it J. Math. Phys.} ! {\bf 22}, 2433 (1981). First, the multipole moments of the muffin-tin charge ! are determined for the $j$th atom of the $i$th species by ! $$ q_{ij;lm}^{\rm MT}=\int_0^{R_i}r^{l+2}\rho_{ij;lm}(r)dr+z_{ij}Y_{00} ! \,\delta_{l,0}\;, $$ ! where $R_i$ is the muffin-tin radius and $z_{ij}$ is a point charge located ! at the atom center (usually the nuclear charge, which should be taken as ! {\bf negative}). Next, the multipole moments of the continuation of the ! interstitial density, $\rho^{\rm I}$, into the muffin-tin are found with ! $$ q_{ij;lm}^{\rm I}=4\pi i^l R_i^{l+3}\sum_{\bf G}\frac{j_{l+1}(GR_i)} ! {GR_i}\rho^{\rm I}({\bf G})\exp(i{\bf G}\cdot{\bf r}_{ij})Y_{lm}^* ! (\hat{\bf G}), $$ ! remembering that ! $$ \lim_{x\rightarrow 0}\frac{j_{l+n}(x)}{x^n}=\frac{1}{(2n+1)!!} ! \delta_{l,0} $$ ! should be used for the case ${\bf G}=0$. A pseudocharge is now constructed ! which is equal to the real density in the interstitial region and whose ! multipoles are the difference between the real and interstitial muffin-tin ! multipoles. This pseudocharge density is smooth in the sense that it can be ! expanded in terms of the finite set of ${\bf G}$-vectors. In each muffin-tin ! the pseudocharge has the form ! $$ \rho_{ij}^{\rm P}({\bf r})=\rho^{\rm I}({\bf r}-{\bf r}_{ij})+\sum_{lm} ! \rho_{ij;lm}^{\rm P}\frac{1}{R_i^{l+3}}\left(\frac{r}{R_i}\right)^l\left(1- ! \frac{r^2}{R_i^2}\right)^{N_i}Y_{lm}(\hat{\bf r}) $$ ! where ! $$ \rho_{ij;lm}^{\rm P}=\frac{(2l+2N_i+3)!!}{2^N_iN_i!(2l+1)!!}\left( ! q_{ij;lm}^{\rm MT}-q_{ij;lm}^{\rm I}\right) $$ ! and $N_i\approx\frac{1}{4}R_iG_{\rm max}$ is generally a good choice. ! The pseudocharge in reciprocal space is given by ! $$ \rho^{\rm P}({\bf G})=\rho^{\rm I}({\bf G})+\sum_{ij;lm}2^{N_i}N_i! ! \frac{4\pi(-i)^l}{\Omega R_i^l}\frac{j_{l+N_i+1}(GR_i)}{(GR_i)^{N_i+1}} ! \rho_{ij;lm}^{\rm P}\exp(-i{\bf G}\cdot{\bf r}_{ij})Y_{lm}(\hat{\bf G}) $$ ! which may be used for solving Poisson's equation directly ! $$ V^{\rm P}({\bf G})=\begin{cases} ! 4\pi\frac{\rho^{\rm P}({\bf G})}{G^2} & G>0 \\ ! 0 & G=0 \end{cases} $$ ! The usual Green's function approach is then employed to determine the ! potential in the muffin-tin sphere due to charge in the sphere. In other ! words ! $$ V_{ij;lm}^{\rm MT}(r)=\frac{4\pi}{2l+1}\left(\frac{1}{r^{l+1}}\int_0^r ! \rho_{ij;lm}^{\rm MT}(r'){r'}^{l+2}dr'+r^l\int_r^{R_i}\frac{ ! \rho_{ij;lm}^{\rm MT}(r')}{{r'}^{l-1}}dr'\right)+\frac{1}{Y_{00}} ! \frac{z_{ij}}{r}\delta_{l,0} $$ ! where the last term is the monopole arising from the point charge. All that ! remains is to add the homogenous solution of Poisson's equation, ! $$ V_{ij}^{\rm H}({\bf r})=\sum_{lm}V_{ij;lm}^{\rm H}\left(\frac{r} ! {R_i}\right)^lY_{lm}(\hat{\bf r}), $$ ! to the muffin-tin potential so that it is continuous at the muffin-tin ! boundary. Therefore the coefficients, $\rho_{ij;lm}^{\rm H}$, are given by ! $$ V_{ij;lm}^{\rm H}=4\pi i^l\sum_{\bf G}j_{l}(Gr)V^{\rm P}({\bf G}) ! \exp(i{\bf G}\cdot{\bf r}_{ij})Y_{lm}^*(\hat{\bf G})-V_{ij;lm}^{\rm MT} ! (R_i). $$ ! Finally note that the ${\bf G}$-vectors passed to the routine can represent ! vectors with a non-zero offset, ${\bf G}+{\bf p}$ say, which is required for ! calculating Coulomb matrix elements. ! ! !REVISION HISTORY: !

Applies the same correction to all the dynamical matrices such that the ! matrix for ${\bf q}=0$ satisfies the acoustic sum rule. In other words, the ! matrices are updated with ! $$ D_{ij}^{\bf q}\rightarrow D_{ij}^{\bf q}-\sum_{k=1}^3 \omega_k^0 ! v_{k;i}^0 v_{k;j}^0 $$ ! for all ${\bf q}$, where $\omega_k^0$ is the $k$th eigenvalue of the ! ${\bf q}=0$ dynamical matrix and $v_{k;i}^0$ the $i$th component of its ! eigenvector. The eigenvalues are assumed to be arranged in ascending order. ! This ensures that the ${\bf q}=0$ dynamical matrix has 3 zero eigenvalues, ! which the uncorrected matrix may not have due to the finite ! exchange-correlation grid. ! ! !REVISION HISTORY: !

The 3-index coupled tensor moment matrices are given by ! $$ \Gamma_t^{kpr}= ! \sqrt{2r+1}\sum_{x=-k}^k\sum_{y=-p}^p ! \begin{pmatrix} k & r & p \\ -x & t & -y \end{pmatrix} ! \Gamma_{xy}^{kp}, $$ ! where the irreducible representations are labeled by $k\in\{0,\ldots,2l\}$, ! $p\in\{0,1\}$, $r\in\{|k-p|,\ldots,k+p\}$ and $\Gamma_{xy}^{kp}$ are the ! uncoupled tensor moments (note that the phase $(-1)^{x+y}$ in the original ! formula has been removed because of the Wigner $3j$ condition $x+y=t$). The ! coupled tensor moment matrices are real and orthonormal in the sense ! $$ \tr\big(\Gamma_t^{kpr}\Gamma_{t'}^{k'p'r'}\big)= ! \delta_{kk'}\delta_{pp'}\delta_{rr'}\delta_{tt'}. $$ ! It can also be shown that the matrices are complete, thus any general ! complex matrix $D$ of dimension $2(2l+1)$ can be expanded as ! $$ D=\sum_{k=0}^{2l}\sum_{p=0}^1\sum_{r=|k-p|}^{k+p}\sum_{t=-r}^r ! z_t^{kpr}\Gamma_t^{kpr} $$ ! where $z_t^{kpr}$ are complex numbers. Likewise, any real matrix can be ! expanded in real tensor moments $w_t^{kpr}$. Using the the symmetry ! properties of the Wigner $3j$-symbols, one can show that the transpose ! $$ \big(\Gamma_t^{kpr}\big)^t=(-1)^{k+p+r+t}\,\Gamma_{-t}^{kpr} $$ ! and thus both the symmetric and antisymmetric parts of $\Gamma_t^{kpr}$ ! transform under rotation within the same irreducible representation. ! Consequently, any complex Hermitian matrix $D$ can be written as ! $$ D=\sum_{k,p,r,t} w_t^{kpr}\big[(\Gamma_t^{kpr})_{\rm S} ! +i(\Gamma_t^{kpr})_{\rm A}\big], $$ ! where the subscripts S and A refer to the symmetric and antisymmetric parts ! of the matrix, respectively.

protex [-hbACFS] ] [+-nlsxf] [src_file(s)] # # !DESCRIPTION: # Perl filter to produce a \LaTeX compatible document # from a DAO Fortran source code with standard Pro\TeX # prologues. If source files are not specified it # reads from stdin; output is always to stdout. # # \noindent # {\bf Command Line Switches:} \vspace{0.2cm} # # \begin{center} # \begin{tabular}{|c|l|} \hline \hline # -h & Help mode: list command line options \\ \hline # -b & Bare mode, meaning no preamble, etc. \\ \hline # -i & internal mode: omit prologues marked !BOPI \\ \hline # +/-n & New Page for each subsection (wastes paper) \\ \hline # +/-l & Listing mode, default is prologues only \\ \hline # +/-s & Shut-up mode, i.e., ignore any code from BOC to EOC \\ \hline # +/-x & No LaTeX mode, i.e., put !DESCRIPTION: in verbatim mode \\ \hline # +/-f & No source file info \\ \hline # -A & Ada code \\ \hline # -C & C++ code \\ \hline # -F & F90 code (default) \\ \hline # -S & Shell script \\ \hline \hline # \end{tabular} # \end{center} # # The options can appear in any order. The options, -h and -b, affect # the input from all files listed on command-line input. Each of the # remaining options effects only the input from the files listed after # the option and prior to any overriding option. The plus sign # turns off the option. For example, the command-line input, # \bv # protex -bnS File1 -F File2.f +n File3.f # \ev # will cause the option, {\tt -n} to affect the input from the files, # {\tt File} and {\tt File2.f}, but not from {\tt File3.f}. The # {\tt -S} option is implemented for {\tt File1} but is overridden by # the {\tt -F} for files {\tt File2.f} and {\tt File3.f}. # # # !SEE ALSO: # For a more detailed description of ProTeX functionality, # DAO Prologue and other conventions, consult: # # Sawyer, W., and A. da Silva, 1997: ProTeX: A Sample # Fortran 90 Source Code Documentation System. # DAO Office Note 97-11 # # # !REVISION HISTORY: # # 20Dec1995 da Silva First experimental version # 10Nov1996 da Silva First internal release (v1.01) # 28Jun1997 da Silva Modified so that !DESCRIPTION can appear after # !INTERFACE, and !INPUT PARAMETERS etc. changed to italics. # 02Jul1997 Sawyer Added shut-up mode # 20Oct1997 Sawyer Added support for shell scripts # 11Mar1998 Sawyer Added: file name, date in header, C, script support # 05Aug1998 Sawyer Fixed LPChang-bug-support-for-files-with-underscores # 10Oct1998 da Silva Introduced -f option for removing source file info # from subsection, etc. Added help (WS). # 06Dec1999 C. Redder Added LaTeX command "\label{sec:prologues}" just # after the beginning of the proglogue section. # 13Dec1999 C. Redder Increased flexbility in command-line # interface. The options can appear in any # order which will allow the user to implement # options for select files. # 01Feb1999 C. Redder Added \usepackage commands to preamble of latex # document to include the packages amsmath, epsfig # and hangcaption. # 10May2000 C. Redder Revised LaTeX command "\label{sec:prologues}" # to "\label{app:ProLogues}" # 10/10/2002 da Silva Introduced ARGUMENTS keyword, touch ups. # # 15Jan2003 R.

This example demonstrates the calculation of the Ca 2p 1/2 - 2p 3/2 (L2 / L3) ! x-ray absorption spectra in CaO. The Ca 2p states are treated as local ! orbitals in Ca_lo.in; additional local orbitals are added to allow an accurate ! description of the unoccupied 3d states (compare with the default version of Ca.in). ! Look at the imaginary part of the spectrum (EPSILON_BSE_11.OUT) in the range 11.8 to ! 12.5 Ha. Compare to the independent-particle calculation (EPSILON_11.OUT). ! Try switching off the exchange and the direct term in the BSE Hamiltonian ! individually (set hxbse/hdbse to .false.). ! For a converged spectrum a lot more k-points (6 x 6 x 6 or more) are needed. ! The numerical cut-offs are well converged, so the computation is quite time ! and memory consuming. Run with hybrid parallelization (MPI across nodes, OpenMP ! across cores) on a cluster for smaller memory footprint. Compare with calculations ! and experimental data in J. Phys. Condens.

In this example, the frequency of a magnon at a particular q-vector in fcc Ni ! is determined. Computing a magnon frequency requires the energy difference, ! dE, between the ferromagnetic and a conical spin-spiral state with small polar ! angle theta. The following formula can then be used to compute the frequency: ! ! w(q) = (4/M) dE / sin^2(theta) ! ! where M is the total moment in the unit cell. See Q. Niu and L. Kleinman, ! Phys. Rev. Lett. 80, 2205 (1998). It is good practice to fix a q and then run ! two fixed spin direction calculations: one at theta=0, and the other at a ! finite theta (in this case 15 degrees). ! Note that the energy difference is very small (order of meV), and the ! calculation has to be very well converged in all parameters. As a result this ! example is best run on a multi-processor, and is still quite time-consuming. tasks 0 stype 1 taufsm 0.01 swidth 0.005 rgkmax 8.0 gmaxvr 14.0 lmaxapw 8 lmaxo 8 ! tight convergence required epspot 1.d-9 epsengy 1.d-6 ! use a fixed spin direction calculation fsmtype -1 ! use a polar angle of 15 degrees momfix 0.0 0.258819045 0.965925826 ! large global field in same direction as momfix bfieldc 0.0 0.258819045 0.965925826 spinsprl .true. ! spin-spiral q-vector in lattice coordinates vqlss 0.1 0.1 0.0 nempty 10 ! very fine k-point grid required for good convergence ngridk 20 20 20 avec 1.0 1.0 0.0 1.0 0.0 1.0 0.0 1.0 1.0 ! experimental lattice parameter scale 3.325 sppath '../../../species/' atoms 1 : nspecies 'Ni.in' : spfname 1 : natoms 0.0 0.0 0.0 0.0 0.0 0.0 : atposl, bfcmt elk-10.4.9/examples/PaxHeaders/basic0000644000000000000000000000013214762655565014305 xustar0030 mtime=1741380469.708014942 30 atime=1741380469.666014723 30 ctime=1741380469.708014942 elk-10.4.9/examples/basic/0000755002504400250440000000000014762655565017104 5ustar00dewhurstdewhurst00000000000000elk-10.4.9/examples/basic/PaxHeaders/Au0000644000000000000000000000013214762655565014652 xustar0030 mtime=1741380469.668014733 30 atime=1741380469.667014728 30 ctime=1741380469.668014733 elk-10.4.9/examples/basic/Au/0000755002504400250440000000000014762655565017451 5ustar00dewhurstdewhurst00000000000000elk-10.4.9/examples/basic/Au/PaxHeaders/elk.in0000644000000000000000000000013214762655565016032 xustar0030 mtime=1741380469.669014738 30 atime=1741380469.668014733 30 ctime=1741380469.669014738 elk-10.4.9/examples/basic/Au/elk.in0000644002504400250440000000125214762655565020554 0ustar00dewhurstdewhurst00000000000000 !

This example illustrates the calculation of X-ray and magnetic structure ! factors which are the Fourier transforms of the electron density and ! magnetisation, respectively. ! !

Since the primitive magnetic unit cell (given by avec) is bigger than the ! conventional crystallographic unit cell (cubic with a = 8.397946), a ! non-integer hkl indices appears when reflections are reindexed to the latter ! with vhmat.

Dielectric function of silicon calculated using real-time evolution. This is ! done with task=481 which assumes that the A-field is constant in time. The ! corresponding electric field is thus proportional to a delta function at t=0 ! and its Fourier transform is a constant in frequency. ! Note that task=480 calculates the same but without assuming that the A-field ! is constant in time. This requires computing J(w)/E(w) which is numerically ! less stable than that obtained with task=481. !

TDDFT time evolution of FeCo with Ehrenfest nuclear dynamics. This is a ! two-step process: first the forces under the influence of a laser pulse are ! calculated. In the second step, the same calculation is repeated but this time ! the forces are used to find the motion of the nuclei. The back-reaction of ! this nuclear motion is applied to the electronic system. ! This approach is valid only for small amplitude nuclear motion. tasks 0 ! ground-state run 450 ! generate the laser pulse A-field 460 ! time evolution with laser pulse and forces calculated 462 ! same time evolution with Ehrenfest dynamics using the previous forces ! calculate forces at each time step tforce .true. ! total simulation time tstime 400.0 ! Simulation time step, ideally about 1 attosecond.

Soft x-ray absorption spectroscopy example for bcc Fe, including XAS, XMCD, ! and XMLD. Species file Fe_lo.in has an additional local orbital at the 2p ! energy. Spin-orbit coupling has to be included for 2p 1/2 - 2p 3/2 splitting. ! XAS, XMCD, and XMLD are computed via first order optical response.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read . -------------------------------------------------------------------------------- GNU LESSER GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1.

See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with Elk. If not, see http://www.gnu.org/licenses/. Elk can be compiled by first editing the file 'make.inc' in this directory to suit your compiler and available libraries, followed by running 'make all'. This will compile the main code as well as several auxiliary programs. A test suite is available: entering 'make test' will check the output of your executable against a standard set. This may take some time to complete. If Elk was compiled with MPI then use 'make test-mpi' instead. The Libxc package can also be tested using 'make test-libxc' (or 'make test-libxc-mpi' with MPI). Auxiliary programs include 'spacegroup' for producing crystal geometries from spacegroup data, and 'eos' for fitting equations of state to energy-volume data. Elk is updated regularly with new features and bug fixes. Features not listed as 'experimental' may be used for production but, as with any code, please check the consistency of your results carefully. -------------------------------------------------------------------------------- J.

This can speed up calculations at the expense of memory -Tyrel McQueen found a bug in the 'findprim' routine, now fixed -TMcQ also suggested a change to how the code connects the points of the 'plot1d' vertices -Martin Stankovski suggested that 'ecvcut' be made into an input variable, allowing the core-valence cut-off to be adjusted -added the phonon calculation of Ni to the examples -Jerzy Goraus contributed a script for calculating VB-XPS spectra from PDOS* files; and also one for converting the Wien2K struct file to spacegroup.in -modified some species files thanks to tests done by J. Goraus -Henning Glawe suggested including the version number in the release directory -upgraded to LAPACK 3.3.0 -made tolerance for finding the linearisation energies (epsband) much smaller: this improves the overall stability of the self-consistent loop Notes for developers -arguments to 'genppts' have changed; also the non-reduced k-points are now stored in the remaining part of the reduced k-point arrays elk-1.1.4 -message passing interface (MPI) parallel runs now available; scalable to hundreds of cores across a cluster; can also be used as hybrid OpenMP+MPI parallelism for maximum efficiency; with thanks to Bhagawan Sahu for help with testing; see manual for compilation and running instructions -S. Sharma added susceptibility tensor for non-linear optical second-harmonic generation (SHG); see example 'GaAs-NLO' for details -added spin-orbit correction to momentum matrix elements; affects linear and non-linear optics -optical calculations now work in combination with spin-spirals -updated interface to version 1.0 of the ETSF exchange-correlation library, libxc; thanks to M. Marques and T. McQueen for assistance -fixed bug spotted by T. McQueen involving using multiple tasks in conjunction with 'primcell=.true.' -A. Kozhevnikov fixed bug in 'xc_pwca.f90' -A. Kozhevnikov also fixed serious bug in 'getevecfv.f90' -F. Cricchio changed the order of lattice vector angles in 'spacegroup' utility to 'bc, ac, ab' which corresponds to the convention alpha, beta, gamma -removed scissor correction from eigenvalue solver; now it is used, as before, only in optics calculations -T. McQueen suggested an improvement to the routine which generates the path in reciprocal space for bandstructure plots, 'connect.f90', which has been implemented -fixed problem with XCrysDen Fermi surface plots, spotted by FC -various optimisations and simplifications Notes for developers -arguments to 'zpotcoul' have changed in anticipation of linear-response phonons; should now be called in conjunction with 'genzvclmt' elk-1.0.17 -fixed problem with Fermi surface generation introduced in the last version -E. K. U. Gross added to list of main developers -no other changes elk-1.0.16 -fixed problem in linear optics calculations for metals - thanks to Antonio Sanna, Fabio Bernardini and Sandro Massida for pointing this out -FC and LN added option for automatic determination of APW linearisation energies (use 'autolinengy=.true.') -Marty Blaber made a script which allows for semi-automatic labeling of the vertex locations with gnuplot (found in the 'elk/utilities' directory) -FC and LN fixed problem with some compilers when writing FERMISURF.OUT -FC and LN fixed problem with writing XCrysDen Fermi surface plots -Anton Kozhevnikov found and fixed a problem with the generation of the irreducible representation file 'ELMIREP.OUT' -Torbjörn Björkman added a new routine which automatically determines the smearing width from the k-point density. See 'autoswidth' in the manual and the example 'Nb-autoswidth' for details -added a constant electric field E in the form of a saw-tooth potential: set the vector 'efieldc' (experimental) -added a constant vector potential A to the Hamiltonian to generate constant currents: set the variable 'afieldc' (experimental) -FC and LN fixed problem with a spin-polarised GGA routine -FC and LN pointed out that the energy term associated with the excess charge compensating background should be zero. This term has now been removed -code now more memory efficient thanks to smarter array allocation -the variable 'rgkmax' can now be made arbitrarily large without risk of instability -removed variable 'cfdamp' -Anton Kozhevnikov pointed out that the radial functions were being redundantly calculated for equivalent atoms -- now fixed -Anton Filanovich added several questions to the FAQ -scissors correction (given by the variable 'scissor') now applied consistently immediately after the generation of the eigenvalues -FC and LN removed the spherical harmonic transform matrices with rank lmmaxapw -added dielectric function calculation for arbitrary q-vector, see 'LiF-Yambo' example (experimental) -by setting 'gmaxvr=0', the G-vector cut-off for the potential and density is automatically determined from 'gmaxvr=2*gkmax+epslat' -various bug fixes, simplifications and optimisations elk-10.4.9/PaxHeaders/Makefile0000644000000000000000000000013014762655567013123 xustar0029 mtime=1741380471.32202338 30 atime=1741380471.321023375 29 ctime=1741380471.32202338 elk-10.4.9/Makefile0000644002504400250440000000101514762655567015644 0ustar00dewhurstdewhurst00000000000000 MAKE = make include make.inc all: cd src; $(MAKE) all cd src/eos; $(MAKE) cd src/spacegroup; $(MAKE) clean: cd src; $(MAKE) cleanall cd src/eos; $(MAKE) clean cd src/spacegroup; $(MAKE) clean rm -f *.o *.mod *~ fort.* ifc* *.gcno *.exe test: cd tests; ./test.sh test-mpi: cd tests; ./test-mpi.sh test-libxc: cd tests-libxc; ../tests/test.sh test-libxc-mpi: cd tests-libxc; ../tests/test-mpi.sh test-all: $(MAKE) test $(MAKE) test-libxc $(MAKE) test-mpi $(MAKE) test-libxc-mpi vim: cd src; ./vimelk elk-10.4.9/PaxHeaders/make.inc0000644000000000000000000000013214762655567013075 xustar0030 mtime=1741380471.334023443 30 atime=1741380471.333023438 30 ctime=1741380471.334023443 elk-10.4.9/make.inc0000644002504400250440000001256214762655567015625 0ustar00dewhurstdewhurst00000000000000 MAKE = make AR = ar # Elk requires BLAS/LAPACK and fast Fourier transform (FFT) libraries. # We recommend using optimised, mutithreaded BLAS/LAPACK libaries such as those # provided by the Intel Math Kernel Library (MKL), OpenBLAS or BLIS. # Elk can use either the Fastest Fourier Transform in the West (FFTW) or the # MKL FFT.
