Entropic fluctuations of open quantum systems.

We discuss the entropic fluctuation relations for the recently developed thermodynamically consistent nonlinear master equation describing open quantum systems out of equilibrium. Such fluctuation theorem is already proven for a Lindblad master equation, based on a deformation of the dissipative generator. We suggest a new way of deforming the generator, which extends to the nonlinear case while still be supported by statistical mechanical arguments, and numerically compute the generating function of the mean entropy transport. We show that the obtained generating function yields fluctuation relations, boiling down to Onsager relations in linear response regime.
