Garcia-Gonzalez, P and Godby, R W (2001) Self-consistent calculation of total energies of the electron gas using many-body perturbation theory. Physical Review B (PRB). 075112. -. ISSN 1098-0121Full text available as:
The performance of many-body perturbation theory for calculating ground-state properties is investigated. We present fully numerical results for the electron gas in three and two dimensions in the framework of the GW approximation. The overall agreement with very accurate Monte Carlo data is excellent, even for those ranges of densities for which the GW approach is often supposed to be unsuitable. The latter seems to be due to the fulfillment of general conservation rules. These results open further prospects for accurate calculations of ground-state properties circumventing the limitations of standard density-functional theory.
