On the influence of the Pauli exclusion principle on the transport properties of dense Coulomb systems
Abstract
Within a model calculation the influence of the Pauli exclusion principle on the electrical conductivity of a fully ionized and degenerate hydrogen plasma is investigated. Basing on a quantum kinetic equation solved with the relaxation time ansatz, the electron — ion contribution to the resistivity is calculated. The thermodynamical Tmatrix for electron — ion scattering processes is evaluated under special account for the Pauli blocking of the intermediate scattering states. The corresponding Bethe — Salpeter equation is solved analytically using a separable approximation of the statically screened potential.The Pauli exclusion principle has been found to give rise for a considerable enhancement of the transport cross section near the Fermi energy. Thus, degeneracy effects tend to diminish the electrical conductivity in the density — temperature region considered here.
