Theory of impurity-concentration dependence of freezing temperatures of metallic spin glasses
(1992-08/01)
The authors present a theory of the freezing temperature Tg of metallic spin glasses. Length scales associated with intrinsic sd scattering and finite temperature play essential roles. They describe an approach in which ...
Wave-vector analysis of metallic surface energy
(1979-10/15)
The exchange and correlation energy of a nonuniform electronic system can be decomposed into contributions of different wave-vector fluctuations. Both the long- and short-wavelength contributions to this energy can be ...
Spin correlations in the low-density electron system
(1993-02/15)
The authors have calculated the spin susceptibility x(q,) within a microscopic model over the full range of densities of the electron liquid in the paramagnetic state. Electron-electron interactions are described by static ...
Nonlocal exchange energy of many-fermion systems of arbitrary dimensionality and interparticle interaction
(1986-11/15)
The exchange contributions to the ground-state energy of an inhomogeneous many-fermion system of arbitrary dimensionality are calculated. Explicit results are given for both the local-density approximation and the lowest-order ...
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 ...
Density dependence of critical magnetic fields at the metal-insulator bifurcation in two dimensions
(APS through AIP, 2003-01/15)
The density dependence of the critical in-plane magnetic field Bc at the bifurcation of the resistivity of two-dimensional electron systems with low levels of disorder is determined using the spin-polarization dependence ...
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 `Quantum-mechanical interpretation of the exchange-correlation potential of Kohn-Sham density-functional theory'
(1990-07/09)
For original paper see M.K. Harbola and V. Sahni, ibid., vol.62, p.489 (1989). Harbola and Sahni suggested a procedure for constructing the exchange-correlation potential that enters the Kohn-Sham single-particle equations. ...
