#### 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

#### Plasmons in disordered, two-component, quasi-two-dimensional electron systems

(1989-08/15)

The authors investigate the effect of elastic scattering of electrons on the properties of plasmons in a disordered, two-component, quasi-two-dimensional electron gas. Numerical results are given for dispersion relations ...

#### 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 ...

#### 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 ...

#### 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 ...

#### 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 ...

#### Convergence properties as a function of spatial dimensionality of gradient expansions for the ground-state energy of an inhomogeneous electron gas

(1986-02/15)

The extended Thomas-Fermi approximation for the ground-state energy of a many-fermion system is generalized to arbitrary spatial dimension. The authors' objective is a better understanding of convergence properties of such ...
