TITLE Nonequilibrium thermodynamics of quantum correlated systems: thermodynamic gain and cost of quantum correlation
ABSTRACT We establish the fluctuation theorem for quantum correlated systems in a bipartite regime where fluctuations of total correlation reconcile a gap between entropy generated by the individual systems and the collective system. While the fluctuations of correlation can be used as a thermodynamic resource, the fluctuation theorem finds an unforeseen thermodynamic cost in a trade-off relation driven by quantum fluctuations. We further show that obtaining statistics of the physical quantities in a time-reversed manner takes advantages to evaluate heat transfer in the resulting thermodynamic relations. We illustrate thermodynamic relations in different scenarios by exploiting our approach.
