Self-Consistent Equations Including Exchange and Correlation Effects
Walter Kohn,L. J. Sham +1 more
TL;DR: In this paper, the Hartree and Hartree-Fock equations are applied to a uniform electron gas, where the exchange and correlation portions of the chemical potential of the gas are used as additional effective potentials.

A Simplification of the Hartree-Fock Method
TL;DR: In this article, the Hartree-Fock equations can be regarded as ordinary Schrodinger equations for the motion of electrons, each electron moving in a slightly different potential field, which is computed by electrostatics from all the charges of the system, positive and negative, corrected by the removal of an exchange charge, equal in magnitude to one electron, surrounding the electron whose motion is being investigated.

Polarizability of a Two-Dimensional Electron Gas
TL;DR: In this paper, the response of a two-dimensional electron gas to a longitudinal electric field of arbitrary wave vector and frequency is calculated in the selfconsistent field approximation, and the results are used to find the asymptotic screened Coulomb potential and the plasmon dispersion for a plane of electrons imbedded in a three-dimensional dielectric.

Electron Correlations at Metallic Densities
TL;DR: In this paper, an improved expression of the dielectric function is given, which includes explicitly, in an approximate way, the short-range correlations arising from both Coulomb and exchange effects by being a functional of the structure factor.

Ground state of the fermion one-component plasma: A Monte Carlo study in two and three dimensions
TL;DR: In this paper, the authors performed fermion Monte Carlo variational calculations to determine the equation of state of the uniform electron one-component plasma in two and three dimensions, and showed that the ground state excess energies calculated by the Monte Carlo method are very precise and in agreement with those of other calculations in the metallic density range and in the very low-density Wigner crystals.
