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

TL;DR

This paper investigates the applicability of generalized Cutler-Mott relations in a two-site charge Kondo circuit, which exhibits both Fermi- and non-Fermi liquid behaviors, across different temperature regimes.

Contribution

It demonstrates that the generalized Cutler-Mott relations are valid in both Fermi- and non-Fermi liquid regimes of the charge Kondo circuit, enabling better characterization of quantum simulators.

Findings

Generalized Cutler-Mott relations hold across temperature regimes.

The relations are applicable to systems with Fermi and non-Fermi liquid properties.

Useful for computing figures of merit of non-Fermi liquid quantum simulators.

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.
