Vienna Ab initio Simulation Package
The Vienna Ab-initio Simulation Package, better known as VASP (or alternatively VAMP), is a package for performing ab-initio quantum mechanical molecular dynamics (MD) using pseudopotentials and a plane wave basis set. VASP is based on CASTEP initially written by Mike Payne at MIT, which was brought to the University of Vienna in Vienna, Austria in July 1989 by Jürgen Hafner. The main program was written by himself, Jürgen Furthmüller, who joined the group at the Institut für Materialphysik in January 1993, and Georg Kresse.
