# Density-functional theory calculations for poly-atomic systems: electronic structure, static and elastic properties and ab initio molecular dynamics

## Description

Abstract The package fhi96md is an efficient code to perform density-functional theory total-energy calculations for materials ranging from insulators to transition metals. The package employs first-principles pseudopotentials, and a plane-wave basis-set. For exchange and correlation both the local density and generalized gradient approximations are implemented. The code has a low storage demand and performs efficiently on low budget personal computers as well as high performance computers. Title of program: fhi96md Catalogue Id: ACTF_v2_0 [ADGY] Nature of problem In poly-atomic systems as for example molecules [1,2], crystals [3,4], defects in crystals [5,6], surfaces [7-9], it is highly desirable to perform accurate electronic structure calculations, without introducing uncontrollable approximations. This enables the predictive description of equilibrium properties as well as of non-equilibrium phenomena for a wide class of materials. Examples studied with the present code or its predecessor include meta-stabilities of defects [5-10}, surface reconstruc ...
