Semiclassics in Density Functional Theory

ORAL

Abstract

Recently, we published an article [1] about the semiclassical origin of density functional theory. We showed that the density and the kinetic energy density of one dimensional finite systems with hard walls can be expressed in terms of the external potential using the semiclassical Green's function method. Here, we show a uniformization scheme for the semiclassical density and the kinetic energy density for turning-point problems.\newline \newline [1] P. Elliott, D. Lee, A. Cangi, and K. Burke, Phys.
