Exchange and correlation energy in a nonuniform fermion fluid
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 ...
Fourth-order gradient contributions in extended Thomas-Fermi theory for noninteracting fermions at finite temperature
Nonlocal corrections to the free energy of a system of noninteracting fermions are considered within the framework of extended Thomas-Fermi theory. The density and temperature dependence of gradient corrections is given ...
Analytical structure of the wave-number-dependent susceptibility of many-fermion systems at low temperature and long wavelength. II
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
