This paper investigates how non-Fermi liquid corrections affect the thermal relaxation time in degenerate electron plasma, showing that NLO NFL corrections further decrease relaxation time compared to LO corrections.

Contribution

It introduces a perturbative calculation of thermal relaxation time including next-to-leading order NFL corrections in degenerate electron plasma.

Findings

NLO NFL corrections reduce relaxation time more than LO corrections

Perturbative expansion in T/m_D used for calculations

Results highlight significance of NFL effects in plasma behavior

Abstract

The thermal relaxation time ($\tau_{\kappa_{ee}}$) for the degenerate electron plasma has been calculated by incorporating non-Fermi liquid (NFL) 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 (NLO). We see that the NLO NFL corrections further reduce the decrease in relaxation time due to the leading order (LO) correction.
