Efficiencies and fluctuations in small out-of-equilibrium devices — •Massimiliano Esposito — Center for Nonlinear Phenomena and Complex Systems, Université Libre de Bruxelles, Campus Plaine CP 231, Brussels B-1050, Belgium.

Small systems undergo strong fluctuations and can easily be driven far from their thermodynamic equilibrium. A stochastic description of their dynamics combined with very few physical assumptions and the correct identification of entropy production provide a consistent nonequilibrium thermodynamic description of these small systems. I will show that such description enables the study of finite-time efficiencies and nonequilibrium fluctuations in various small devices such as thermoelectric quantum dots and photoelectric cells.
