“…We remark that, besides the system studied in this paper, many equilibrium thermodynamic properties have been investigated in different conditions, theoretically and experimentally: thermodynamics of rings interrupted by insulating Josephson Junction [ 71 , 72 , 73 , 74 , 75 ], heat capacity in SN systems [ 76 , 77 , 78 ], free energy in hybrid SN systems due to boundary effects with approaches different to the quasi-classical theory [ 79 , 80 , 81 ].…”

We study the thermodynamic properties of a superconductor/normal metal/superconductor Josephson junction in the short limit. Owing to the proximity effect, such a junction constitutes a thermodynamic system where phase difference, supercurrent, temperature and entropy are thermodynamical variables connected by equations of state. These allow conceiving quasi-static processes that we characterize in terms of heat and work exchanged. Finally, we combine such processes to construct a Josephson-based Otto and Stirling cycles. We study the related performance in both engine and refrigerator operating mode.
