Theoretical study the heat rectification via a superconducting artificial atom — •Meng Xu, Juergen Stockburger, and Joachim Ankerhold — Institute for Complex Quantum Systems and IQST, University of Ulm, 89069 Ulm, Germany

Rectification of heat transfer at nanoscales have received increasing attention in theoretical and experimental fields. Here, We theoretically studied the heat rectification via a superconducting artificial atom where a superconducting transmon qubit coupled to two strongly unequal resonators terminated by mesoscopic heat baths. In the simulations, we have combined Hierarchical equations of motion (HEOM) and tensor network (TN) methods to efficiently study this complex system dynamics.
