TL;DR

This paper derives and analyzes transport coefficients in fully ionized plasma with kappa-distribution under strong magnetic fields, highlighting the dependence on the kappa-parameter and recovering classical results as kappa approaches infinity.

Contribution

It provides new analytical expressions for transport coefficients in kappa-distributed plasma under strong magnetic fields, extending traditional Maxwellian-based models.

Findings

Transport coefficients depend strongly on the kappa-parameter.

In the limit kappa to infinity, classical plasma transport coefficients are recovered.

Numerical analysis shows the influence of kappa on transport properties.

Abstract

Transport processes in the fully ionized plasma with kappa-distribution and in strong magnetic field are studied. By analyzing the current density and the heat flux in the kappa-distributed plasma, we derive the corresponding transport coefficients, including the electric conductivity, the thermal conductivity and thermoelectric coefficient. Besides, we derive the coefficients of Hall, Nernst and Leduc-Righi effects in the kappa-distributed plasma. It is shown that these new transport coefficients depend strongly on the kappa-parameter and only in the limit kappa to infinity, they recover the traditional forms in the plasma based on a Maxwellian distribution. We also numerically analyze the role of the kappa-parameter in the kappa-dependent transport coefficients.
