Landau Fermi-liquid theory of NMR relaxation times

Abstract

Landau Fermi-liquid theory has long been a standard method for describing the low-temperature behavior of the normal phase of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$. Here we review some of the known thermodynamic and transport results from the viewpoint of the fluctuation-response theorems. The fluctuation formulation is then applied to the case of nuclear-magnetic-resonance relaxation times, and from this a theoretical prediction is made for $T_1$ in normal liquid ${}_{}{}^3{}_{}{}^{}\mathrm{He}$.
