Atomistix ToolKit is a further development of the TranSIESTA method.īAND, which is part of the Amsterdam Density Functional (ADF) package, is a full-potential LCAO DFT code for general periodicity: molecules, linear chains, surfaces, and solids. (Licence Details: If you are interested in the ASW package please contact Volker Eyert – )Ī combination of density functional theory and non-equilibrium Green’s function methods makes Atomistix ToolKit an efficient and powerful tool for calculating and understanding intrinsic properties of nanoscale systems. It allows for scalar-relativistic calculations and spin-restricted and spin-polarized calculations and is well suited for both close-packed and open crystal structures (automated sphere packing – generation of empty spheres, optimal atomic sphere radii). It is characterized by a minimal basis set (atomic-like ( s, p, d) basis functions / high computational speed / simple interpretation of results). It is an all-electron method (core electrons fully included / full coverage of the periodic table / applicable to metals, semiconductors and insulators). The Augmented Spherical Wave method is based on the Born-Oppenheimer approximation density functional theory and uses the Local Density Approximation (LDA), the Generalized Gradient Approximation (GGA), the Muffin-Tin Approximation (MTA) and Atomic Sphere Approximation (ASA). ( Licence Details: ABINIT is distributed under the GNU General Public Licence) In addition to the main ABINIT code, various utility programs are provided. Excited states can be computed within time-dependent density functional theory (for molecules), or within many-body perturbation theory (the GW approximation). ABINIT also includes options to optimise the geometry according to the DFT forces and stresses, or to perform molecular dynamics simulation using these forces, or to generate dynamical matrices, Born effective charges, and dielectric tensors.

If you are an author or user of one of the codes here, or of a code that should be listed here but isn’t, please contact us if you wish to update the information we provide: ĪBINIT is a package whose main program allows one to find the total energy, charge density, and electronic structure of systems made of electrons and nuclei (molecules and periodic solids) within density functional theory (DFT), using pseudopotentials and a plane-wave basis.

Links to home pages are given where possible, together with a short description and some details about licensing. Here is a list of software codes that may be used to perform the sort of research of interest to the Psi-k community.
