On the conductivity of moderately non-ideal completely ionized plasma

Abstract

Interrelations between the problems of electrical conductivity of a completely ionized plasma and the ion drag force in a dusty plasma are discussed. It is shown that a physically motivated modification of the Coulomb logarithm proposed in the context of ion-particle scattering in dusty plasma allows us to improve the theoretical description of the conductivity in the moderately non-ideal regime. A simple theoretical expression obtained is in reasonable agreement with available results from experiments and numerical simulations.
