Dynamic Response of Inhomogeneous Fermi Systems.

Abstract

This paper presents a theory of the linear density response to an external time dependent scalar potential for a Fermi system whose unperturbed density varies slowly on a scale l >> 1/p sub F, where p sub F is a characteristic Fermi momentum. Simple local density functional response theory is valid except in a region of small q and omega (wave number and frequency of the perturbation). For this region we have worked out a generalization, to the case of inhomogeneous systems, of the classical Landau Fermi liquid theory. (Author)
