Generalized Cutler-Mott relation in a two-site charge Kondo simulator

Abstract

We analyze the validity of the Cutler-Mott relations outside the Landau Fermi-liquid concept. We consider a two-site charge Kondo circuit as a paradigmatic example of a system possessing both Fermi- and non-Fermi liquid properties. It is shown that the generalized Cutler-Mott-like relations derived in the paper hold in both operating regimes of the charge Kondo quantum circuit describing a smooth crossover between low- and high- temperature regimes. We discuss applicability of the generalized Cutler-Mott relations for computing a figure of merit of the non-Fermi liquid quantum simulators.
