Generalized local-density approximation and one-dimensional finite uniform electron gases

Loos, Pierre-Francois

Description

We explicitly build a generalized local-density approximation (GLDA) correlation functional based on one-dimensional uniform electron gases (UEGs). The fundamental parameters of the GLDA - a generalization of the widely known local-density approximation used in density-functional theory - are the electronic density ρ and a two-electron local parameter called the hole curvature η. The UEGs considered in this study are finite versions of the conventional infinite homogeneous electron gas and...[Show more]
