Driven Magnon-Photon System as a Tunable Quantum Heat Rectifier

Abstract: Controlling the flow of heat in quantum systems or circuits is very desirable for the development of quantum technologies. Here, we investigate the quantum heat transport in a driven hybrid magnonphoton system in contact with two thermal baths operating at different temperatures. Specifically, we analyze the role of the parameters of the hybrid quantum system in the processes that lead to the asymmetry of the steady-state heat current. We find that the thermal rectification is high in the regime of weak magnon-photon hybridization strength and large magnon-drive. Moreover, this driving and the system parameters could serve as experimental knobs to tune the thermodynamic properties of the magnon-photon system, as we demonstrate for the rectification parameter tunable by the drive in its entire physical range. The results from this research would provide very useful insight into the design of quantum thermal machines with a driven magnon-photon system.
