TLDR
In this article, a self-consistent quasistatic screening approach was proposed for studying the properties of an interacting electron gas, and the compressibility divergence and the ferromagnetic instability found in the static unscreened Hartree-Fock approximation are nonexistent in this scheme.Abstract:
A new self-consistent quasistatic screening approach is proposed for studying the properties of an interacting electron gas. The compressibility divergence and the ferromagnetic instability found in the static unscreened Hartree-Fock approximation are nonexistent in this scheme. A better fit to the experimental data on the plasma dispersion relation than the existing calculations for free-electron metals is obtained.read more

On the temperature dependence of the magnetic susceptibility of liquid alkali metals
TL;DR: In this paper, the temperature dependence of the magnetic susceptibility of liquid Na and Cs has been re-examined experimentally and it was shown that magnetic susceptibility decreases with rising temperature, although for liquid Na, K and Rb it increases with temperature

Some results in the theory of interacting electron systems
TL;DR: In this paper, the expressions for the longitudinal dielectric function, spin and orbital susceptibilities in the static, long wavelength limit are evaluated by solving the corresponding linearized vertex functions exactly in this limit.

The effective interparticle screening and the local-field correction in the spin-polarized electron system
S. V. Ivliev,V. N. Sobakin +1 more
TL;DR: The screening properties of a system of interacting spin-polarized electrons are investigated in this paper, where the exact closed equation for the vertex function is received by a many-particle approach and the main contribution to that function is founded on the linear approximation of the generalized screened potential.
