Non-Fermi liquid behavior of thermal relaxation time in degenerate electron plasma

Abstract

The thermal relaxation time (${\ensuremath{\tau}}_{{\ensuremath{\kappa}}_{\mathrm{ee}}}$) for the degenerate electron plasma has been calculated by incorporating non-Fermi liquid corrections both for the thermal conductivity and specific heat capacity. Perturbative results are presented by making expansion in $T/{m}_{D}$ with next to leading order corrections. We see that the next to leading order non-Fermi liquid corrections further reduce the decrease in relaxation time due to the leading order corrections.
