Energetics of an rf SQUID Coupled to Two Thermal Reservoirs.

Energetics of an rf SQUID Coupled to Two Thermal Reservoirs.

We study energetics of a Josephson tunnel junction connecting a superconducting loop pierced by an external magnetic flux (an rf SQUID) and coupled to two independent thermal reservoirs of different temperature. In the framework of the theory of quantum dissipative systems, we analyze energy current...
