Kristallogr. 220, 558 (2005)] ] is a free software package for
physicist s, distributed under theGNU General Public License , whose main program allows the totalenergy , charge density, and electronic structure of systems made ofelectron s and nuclei (molecules and periodic/crystallinesolid s) to be calculated withinDensity Functional Theory (DFT), usingpseudopotential s, and aplane wave basis.ABINIT also includes options to
* optimize thegeometry according to the DFT forces and stresses;
* performmolecular dynamics simulation s using these forces; and
* generate dynamical matrices, Born effective charges, anddielectric tensor s.Excited state s can be computed within the Time-Dependent Density Functional Theory (for molecules), or within Many-Body Perturbation Theory (theGW approximation ). In addition to the main ABINITcode , differentutility program s are also provided.See also
