Development of the Vienna ab initio simulation package (VASP).
The program package is widely used for the simulation of
periodic and non-periodic condensed (solid or liquid) matter
systems. VASP computes approximate solutions to the many-body Schrödinger equation,
either within density functional theory (DFT), solving the Kohn-Sham equations,
or within the Hartree-Fock (HF) approximation, solving the Roothaan equations.
Hybrid functionals that mix the Hartree-Fock approach with density functional theory
are available as well. Furthermore, Green's functions methods (GW quasiparticles, and ACFDT-RPA)
and many-body perturbation theory (2nd-order Møller-Plesset) can be used.
Development and application of quantum chemistry methods to solids.
This includes simple perturbation theory such as Møller Plesset 2,
as well as coupled cluster (CCSD, CCSD(T)) methods adopted to periodic systems.
Application of full CI methods to the solid state.
Development of approximate but accurate many body schemes for the solid state,
including the random phase approximation and corrections mitigating
the main deficiencies of the random phase approximation.
Time dependent properties using TD-DFT (direct diagonalization as well
as time evolution methods). Development of two particle Greens function based
such as the Bethe Salpeter and Parquet equation and adoption of these methods
to solid and molecular systems.
