Exchange and correlation energy in a nonuniform fermion fluid
(1986-07/15)
Recent results for the surface energy of jelliumlike surfaces are investigated within the functional-density formalism. These results along with first-principles considerations support the contention that the first gradient ...
Small and large wavelength contributions to the exchange and correlation energy of a nonuniform electron gas
(1982-04/15)
For the uniform electron gas, the decomposition of the exchange and correlation energy into its individual wave vectors has proved invaluable for both a deeper understanding of its structure as well as its extensions to ...
Wave-vector decomposition of the exchange and correlation contributions to a metallic surface energy
(1980-04/15)
The authors decompose the lowest-order nonlocal corrections to the local-density approximation to the exchange and correlation component of the metallic surface energy in terms its wave-vector components. Comparison with ...
Comment on `Exact electron-gas response functions at high density'
(1988-05/09)
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 ...
Analytical structure of the wave-number-dependent susceptibility of many-fermion systems at low temperature and long wavelength. II
(1980-10/15)
For pt.I see ibid., vol.15, p.1523 (1977). It is shown that the nonanalytic structure of the wave-number-dependent susceptibility noted by Geldart and Rasolt is not removed by including repeated particle-particle scattering
