Finite-freauency thermoelectric response in strongly correlated quantum dots

We investigate the finite-frequency thermal transport through a quantum dot subject to strong interactions by providing an exact, nonperturbative formalism that allows us to carry out a systematic analysis of the thermopower at any frequency. Special emphasis is put on the dc and high-frequency limi...

Description
Summary:We investigate the finite-frequency thermal transport through a quantum dot subject to strong interactions by providing an exact, nonperturbative formalism that allows us to carry out a systematic analysis of the thermopower at any frequency. Special emphasis is put on the dc and high-frequency limits. We demonstrate that, in the Kondo regime, the ac thermopower is characterized by a universal function that we determine numerically.
