Comment on `Exact electron-gas response functions at high density'

Abstract

For original paper see D.C. Langreth and S.H. Vosko, ibid., vol.59, p.497 (1987). Langreth and Vosko calculated correlation contributions to the Hohenberg-Kohn energy response function Kxc(q,k). They claimed that the results supported the Langreth-Mehl (LM) treatment of the interacting nonuniform electron gas. The authors point out a number of serious deficiencies of LM. A reply by Langreth and Vosko is included
