Charge and heat transport in a charge 2 channel Kondo device

Recently, the charge two channel effect was realized in an experimental setup for the first time. Remarkably, the scaling curve of the critical conductance was measured over many decades and was in excellent agreement with theoretical calculations. In this talk we focus on the heat transport in the setup. We theoretically show a violation of the Wiedemann-Franz law and point out an interesting connecting to the central charge of one dimensional Majorana fermions.
