Thermoelectric transport across a tunnel contact between two charge Kondo circuits: beyond perturbation theory
arXiv:2306.12229 · doi:10.1103/PhysRevB.109.115139
Abstract
Following a theoretical proposal on multi-impurity charge Kondo circuits [T. K. T. Nguyen and M. N. Kiselev, Phys. Rev. B {\bf 97}, 085403 (2018)] and the experimental breakthrough in fabrication of the two-site Kondo simulator [W. Pouse {\it et al}, Nat. Phys. (2023)] we investigate a thermoelectric transport through a double-dot charge Kondo quantum nano-device in the strong coupling operational regime. We focus on the fingerprints of the non-Fermi liquid and its manifestation in the charge and heat quantum transport. We construct a full-fledged quantitative theory describing crossovers between different regimes of the multi-channel charge Kondo quantum circuits and discuss possible experimental realizations of the theory.
