Non-Fermi liquid behavior of thermal relaxation time in degenerate
electron gas
   [PDF]

Sreemoyee Sarkar, Abhee K. Dutt-Mazumder
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. It is seen that unlike the normal Fermi liquid (FL) result where $\tau_{\kappa_{ee}}\propto 1/T^2$, NFL corrections in leading order (LO) changes the temperature dependence of $\tau_{\kappa_{ee}}$ to 1/T. Incorporation of the phase space correction driven by the medium modified Fermion dispersion relation increases the relaxation time further.
