Low rank factorization of the Coulomb integrals for periodic coupled cluster theory
Felix Hummel, Theodoros Tsatsoulis, Andreas Grüneis
We study the decomposition of the Coulomb integrals of periodic systems into a tensor contraction of six matrices of which only two are distinct. We find that the Coulomb integrals…

Screened exchange corrections to the random phase approximation from many-body perturbation theory
Felix Hummel, Andreas Grüneis, Georg Kresse +1
The random phase approximation (RPA) systematically overestimates the magnitude of the correlation energy and generally underestimates cohesive energies. This originates in part fr…
