Density Functional Theory from the Extreme Limits of Correlation

  • Michael Seidl
Chapter

Abstract

The difficulty of the quantum-mechanical many-body problem of atoms, molecules, solids, etc. is mainly due to the mutual Coulomb repulsion between the electrons. In Hartree-Fock theory, this two-particle interaction is approximated by an effective single-particle potential. In terms of the rest interaction, the perturbation theory by Møller and Plessetl provides a weak-interaction expansion for the ground state energy. If carried to high orders, however, this expansion seems to diverge even in cases as promising as the neon atom.2
