Critical exponents and amplitude ratios from electrical resistivity measurements of dysprosium
(1980-02/01)
Resistive anomalies in helical antiferromagnets are shown to reflect the temperature dependence of the specific heat sufficiently close to the Neel temperature. The temperature dependence of superzone energy gaps does not ...
Adsorbate densities and surface potentials of physisorbed systems: A density-functional approach
(1987-06/15)
A density-functional approach for the calculation of the density of particles adsorbed on the surface of a solid is explored including the adparticle two-body interaction. The coverages and effective surface potentials so ...
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 ...
Comment on `Anisotropic superconductors with repulsive average interaction'
(1982-10/01)
For original paper see M.D. Whitmore and J.P. Carbotte, ibid., vol.23, p.5782 (1981). In a recent paper Whitmore and Carbotte concluded that a sufficient condition for the superconducting state to be stable relative to the ...
Magnetic susceptibility of metallic transition-metal dichalcogenides
(1981-07/01)
A tight-binding model has been used to estimate the anisotropy of the magnetic susceptibility of the metallic transition-metal dichalcogenides. The calculated anisotropies obtained are in qualitative agreement with ...
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 ...
Fourth-order gradient contributions in extended Thomas-Fermi theory for noninteracting fermions at finite temperature
(1985-12/15)
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 ...
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 ...
