Dissipation by thermal forces in quantum plasmas
Abstract
This paper deals with degenerate FermiDirac plasmas in which transport is by quasiparticles that form a dilute gas described by the Boltzmann equation. The offequilibrium part of the distribution function of each species is estimated by expanding it in terms of the fluid velocity of the species, relative to the plasma, and its relative heat flux vector. Expressions for the frictional forces acting between the species, consisting of a relaxationmodel force and a thermal force, are obtained. These are used in a plasma dissipation formalism, yielding, for ternary partially ionized plasmas, a generalized Ohm law and an ambipolar diffusion law. The results are applied to neutron star matter, consisting of thermally ultrarelativistic electrons and nonrelativistic protons and neutrons, with the mass density dominated by the neutrons. The dissipation formalism is used to obtain an expression for the magnetic force on this material.
