The Slater Approximation of the Hartree-Fock
Exchange Term : Rigorous Derivation via Deformations
Abstract
We present a method for the derivation of local approximations of
the exchange-term
in the Hartree-Fock equation for a system of fermions interacting with a
Coulomb-force. Within our model, we give a justification of the
Slater-approximation where the exchange term is replaced by the third
root of the local density. Our approach is based on deformations, i.e.
local scaling transformations of the constant density of plane waves,
combined with the "high density limit" of an infinite number of particles.
