Geometric energy transport and refrigeration with driven quantum dots

Geometric energy transport is of high interest both for spectroscopy of quantum devices and as a way to realize cyclic thermal machines at the nanoscale. Using a recently discovered dissipative symmetry, this work derives compact and insightful analytical expressions characterizing energy pumping with a slowly driven quantum dot subject to strong many-body interactions. Equipped with these results, the authors analyze the dot as a refrigerator or a heat pump, revealing a direct link between its efficiency and its well-known steady-state thermoelectric properties.
