Universality of the Hohenberg-Kohn functional

Physics Education 2007-05-23 v1 Materials Science

Abstract

We comment on a recent article by H. L. Neal [Am. J. Phys. 66, 512 (1998)], in which an analytic expression for the Hohenberg-Kohn functional was derived for one-dimensional two-particle systems with the harmonic interaction. We argue that the functional given by Neal is not exact but really constitutes an approximation in the same spirit as the local-density approximation.
