Diamagnetic susceptibility of a dense electron gas
(1988-02/15)
The authors calculate the diamagnetic susceptibility of a uniform interacting electron gas in the random-phase approximation. From this the exact high-density expansion of the diamagnetic susceptibility is obtained
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 ...
Critical magnetic susceptibility of gadolinium
(1988-08/01)
The magnetic suspectibility of a single crystal of high-purity gadolinium has been measured in the critical region with use of AC susceptibility methods. For reduced temperatures t10-3, the data are described by a simple ...
Coefficients to O(3) for the mixed fixed point of the nm-component field model
(1985-10/01)
The nm-component field model has a number of application in the description of critical phenomena. The coefficients in the expansion for the stability matrix eigenvalues and correlation function exponent n for the mixed ...
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 ...
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 ...
Surface-induced quantum density oscillations in the presence of an external magnetic field
(1985-03/15)
The electron number density and spin density near the surface of a model metal, semimetal, or semiconductor are calculated in the presence of a uniform magnetic field. The magnetic field is applied in a direction perpendicular ...
Dipole-dipole interactions and the critical resistivity of gadolinium
(1987-06/01)
Results are presented for the electrical resistivity of a c-axis single crystal of high-purity gadolinium metal in the immediate vicinity of the Curie temperature. Numerical analysis reveals that the data are not well ...
