MBPT_LCAO
MBPT_LCAO is abbreviation for Many-Body Perturbation Theory (MBPT) done with Linear Combination of Atomic Orbitals. The package is a tool to determine and analyze electronic structure of matter. The so far implemented features include Hartree-Fock (HF), time-dependent density functional theory (TDDFT), Hedin's GW calculations for finite systems (molecules, atoms) and TDDFT for bulk systems.
