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 ...
Temperature dependent resistivity in the low-resistance region for diffusive transport in two dimensions
(APS through AIP, 2004-12/15)
The interpretation of the metal-insulator transition phenomena in disordered two-dimensional electron systems in terms of density-dependent scaling variables suggests the existence of a quantum critical point at some ...
Quantum critical behavior in the insulating region of the two-dimensional metal-insulator transition
(American Physical Society by AIP, 2007-11/15)
We show that the quantum critical point associated with the metal-insulator transition phenomenon in two dimensions controls an extended critical region encompassing not only the usual quantum critical sector but also a ...
Gradient corrections in the exchange and correlation energy of an inhomogeneous electron gas
(1975-11/03)
A closed form expression for the coefficient Bxc which determines the first gradient corrections to the exchange and correction energy is derived. The exact expression is obtained from an approximation that includes the ...
Two-component scaling near the metal-insulator bifurcation in two dimensions
(APS through AIP, 2003-05/15)
We consider a two-component scaling picture for the resistivity of two-dimensional (2D) weakly disordered interacting electron systems at low temperature with the aim of describing both the vicinity of the bifurcation and ...
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 ...
