Correlation energies in the random phase approximation using realistic interactions
Barbieri, C, Paar, N, Roth, R and Papakonstantinou, P (2006) Correlation energies in the random phase approximation using realistic interactions
Full text not available from this repository.Abstract
The self-consistent random phase approximation (RPA) based on a correlated realistic nucleon-nucleon interaction is used to evaluate correlation energies in closed-shell nuclei beyond the Hartree-Fock level. The relevance of contributions associated with charge exchange excitations as well as the necessity to correct for the double counting of the second order contribution to the RPA ring summation are emphasized. Once these effects are properly accounted for, the RPA ring summation provides an efficient tool to assess the impact of long-range correlations on binding energies throughout the whole nuclear chart, which is of particular importance when starting from realistic interactions.
