Garcia-Gonzalez, P and Godby, R W orcid.org/0000-0002-1012-4176 (2002) Many-body GW calculations of ground-state properties: Quasi-2D electron systems and van der Waals forces. Physical Review Letters. 056406. -. ISSN 1079-7114
Abstract
We present GW many-body results for ground-state properties of two simple but very distinct families of inhomogeneous systems in which traditional implementations of density-functional theory (DFT) fail drastically. The GW approach gives notably better results than the well-known random-phase approximation, at a similar computational cost. These results establish GW as a superior alternative to standard DFT schemes without the expensive numerical effort required by quantum Monte Carlo simulations.
