Kohn-Sham calculations combined with an average pair-density functional theory

TL;DR

This paper reviews a formalism combining Kohn-Sham calculations with average pair-density functional theory, introduces new properties of the effective electron-electron interaction, and presents a preliminary self-consistent scheme.

Contribution

It introduces a novel combination of Kohn-Sham and average pair-density functional theory with new insights into the effective electron-electron interaction and a preliminary self-consistent approach.

Findings

Derived new properties of the effective electron-electron interaction.

Presented a preliminary self-consistent scheme within the formalism.

Reviewed the formalism integrating Kohn-Sham calculations with average pair-density functional theory.

Abstract

A recently developed formalism in which Kohn-Sham calculations are combined with an ``average pair density functional theory'' is reviewed, and some new properties of the effective electron-electron interaction entering in this formalism are derived. A preliminary construction of a fully self-consitent scheme is also presented in this framework.
