Proposal for a two-channel quantum dot setup: Prediction for the capacitance lineshape

Abstract

We have made a detailed proposal for a two-channel quantum dot setup. The energy scales in the problem are such that we are able to make connection with the two-channel Anderson model, which, in spite of being well-known in the context of heavy-Fermion systems remained theoretically elusive until recently and lacked a mesoscopic realization. Verification of our precise and robust predictions for the differential capacitance lineshape of the dot will provide an experimental signature of the two-channel behavior.
