ON THE THEORETICAL FOUNDATION OF THE ONE-ELECTRON APPROXIMATION

Abstract

Identifiers: Fermion systems, Sweden. The first part of this paper contains a qualitative discussion of the one-electron approximation and a rough review of the Bohm-Pines, van HoveHugenholtz and Luttinger work. These works can be considered as representative of that part of current many-body literature which aims directly at the behavior of quasi-particles in normal many-fermion systems. The second part tries to elaborate a specific method to handle quasiparticles. The method is formally similar to the usual Hartree-Fock scheme and it was chosen out of many possible approaches partly because the author has been actively working with it and partly because it is fairly simple and still illustrates the ideas and scope of present day many-body theories.
