Local density approximation for longrange or for shortrange energy functionals?
Abstract
Density functional methods were developed, in which the Coulomb electronelectron interaction is split into a long and a shortrange part. In such methods, one term is calculated using traditional density functional approximations, like the local density approximation. The present paper tries to shed some light upon the best way to do it by comparing the accuracy of the local density approximation with accurate results for the He atom.
