Quasi-classical theory of electron correlations in atoms.

Donald F. DuBois, M. G. Kivelson

ResearchPublished 1962

A discussion of the quasi-classical limit of many particle perturbation theory for electrons moving in the coulomb potential of the nucleus. The problem is analyzed using Green's function formu- lation of many particle physics. When corrections involving the gradient of the self-consistent potential are neglected, the results agree to all orders in the interaction strength with the procedure of Lewis for including correlation corrections in the Thomas-Fermi model. The disagreement between the work of Lewis and the recent work of Baraff is shown to be due to the latter's neglect of anomalous contributions to the perturbation theory. These contributions arise because the local Fermi momentum is a function of the interaction strength. The calculation of inhomogeneity cor- rections is also considered.
