Polarons in the layered electron gas

Physical Review B, 1991
In a layered electron gas, optical phonons which vibrate with their polarization parallel to the c axis are relatively unscreened when the conduction electrons can move only within the planes. We calculate the electron-phonon interaction between the conduction electrons and these parallel phonons. We show that the interaction is very weak.

Diffusion and fluctuations in a nonequilibrium electron gas with electron-electron collisions

Physical Review B, 1989
We investigate the equivalence between the Boltzmann (or field) approach and the particle approach for the definition of the diffusion coefficient in the presence of electron-electron collisions. Accordingly, we introduce a ‘‘model’’ collision operator as well as a ‘‘model’’ electron distribution function which can be used in a one-particle numerical ...

Renormalization Constant of Electron Gas

Journal of the Physical Society of Japan, 1963
An evaluation is carried out for the renormalization constant Z of an interacting electron gas. It is shown that the lowest approximation with respect to effective interaction between electrons leads to Daniel and Vosko's result for Z , while higher order correction for Z modifies their result appreciably and their result is not correct even in the ...

Spin Susceptibility of an Electron Gas

Physical Review, 1960
The generalized random phase approximation is used to investigate the effects of electron-electron interaction on the spin susceptibility of an electron gas. Within this approximation, the induced spin density is determined by the solution of an integral equation that describes exchange scattering between virtually excited particles.

Viscosity of the Electron Gas in Metals

Physical Review, 1958
With a view toward explaining measurements of ultrasonic attenuation in metals, the coefficient of shear viscosity of a free electron gas interacting with thermal phonons and local crystal inhomogeneities is computed. The methods employed are essentially those developed for the problem of electrical conductivity.

The influences of gas and electron temperatures on electron attachment in gas electrical discharges

Czechoslovak Journal of Physics, 1998
Various electron attachment processes are reviewed, emphasising the way in which the rates and products of some selected reactions vary with the attaching gas temperatureT g, the temperature,T e, and the energy of the attaching electrons.

Kinetic energy of an electron gas

Physical Review B, 1985
We derive a simple expression for the correlation part of the kinetic energy of an inhomogeneous electron gas from density-functional theory. We show that in the local density approximation, this expression reduces to the virial theorem result ${t}_{\mathrm{xc}}=3{v}_{\mathrm{xc}}\ensuremath{-}4{\ensuremath{\epsilon}}_{\mathrm{xc}}$. We also derive the

Diamagnetism of a Dense Electron Gas

Physical Review, 1957
The theory of Coulomb interactions in a dense electron gas at zero temperature is formally simplified by the introduction of an equivalent Hamiltonian which gives the correct high-density value for the correlation energy. In the corresponding approximation, the diamagnetism of a dense electron gas is found to be the same as that of noninteracting ...
