Page "Vienna Ab-initio Simulation Package" Paragraph 0

The Vienna Ab-initio Simulation Package, better known as VASP, is a package for performing ab initio quantum mechanical molecular dynamics ( MD ) using either Vanderbilt pseudopotentials, or the projector augmented wave method, and a plane wave basis set.

The basic methodology is Density Functional Theory ( DFT ), but the code also allows use of post-DFT corrections such as hybrid functionals mixing DFT and Hartree-Fock exchange, many-body perturbation theory ( the GW method ) and dynamical electronic correlations within the random phase approximation.
