Coulomb blockade oscillations of heat conductance in the charge Kondo regime

We develop a method of theoretically investigating the charge, energy, and heat transport in the presence of the charge Kondo correlations. The Coulomb blockade oscillations of heat conductance in the single-electron transistor exhibiting charge Kondo effects are investigated. We explore the Wiedemann-Franz ratio in both charge-single-channel and charge-two-channel Kondo regimes. The close connections of our findings with the recent experiments on multichannel charge Kondo effects are discussed.
