Thermal transport in a charge two-channel Kondo setup

The original Kondo model describes the behaviour of a non-magnetic metal containing a single magnetic impurity. Motivated by the experimental realization of a remarkable quantum dot device [Iftikhar et al., Nature 526, 233 (2015)], we consider the more complicated charge two-channel Kondo (2CK) model. In particular, we discuss the thermal transport properties of this 2CK model due to a temperature gradient between the leads. We propose that the corresponding heat conductance provides a way to experimentally verify the Majorana character of the dot region at the critical non-Fermi liquid point.
