TL;DR

This paper derives expressions for transport coefficients in Lorentz plasmas with a power-law kappa-distribution, showing how they depend on the kappa-parameter and reduce to standard forms for Maxwellian distributions.

Contribution

It provides new analytical expressions for electric conductivity, thermoelectric coefficient, and thermal conductivity in Lorentz plasmas with kappa-distribution.

Findings

Transport coefficients depend significantly on the kappa-parameter.

In the limit of kappa to infinity, coefficients reduce to Maxwellian plasma values.

Expressions are derived without magnetic field influence.

Abstract

Transport coefficients in Lorentz plasma with the power-law kappa-distribution are studied by means of using the transport equation and macroscopic laws of Lorentz plasma without magnetic field. Expressions of electric conductivity, thermoelectric coefficient and thermal conductivity for the power-law kappa-distribution are accurately derived. It is shown that these transport coefficients are significantly modified by the kappa-parameter, and in the limit of the parameter kappa to infinit they are reduced to the standard forms for a Maxwellian distribution.modified
