Interparticle interaction potential in two-component plasmas

Abstract

The purpose of this work is to find a pseudopotential of interparticle interaction of charged particles which takes into account quantum and collective effects for an ideal and weakly non ideal plasma in the framework of linear dielectric response formalism. In the quantum contribution to the potential the symmetry effects are neglected. Fourier transformations are employed in our studies of the potential. The results demonstrate that the constructed potential is finite at the origin and tends to the Coulomb one when the interparticle distance tends to infinity. In other words, it satisfies established theoretical requirements. The potential we obtain is also compared to the well-known Debye-Hückel and Deutsch potentials.
