Pierre Gaspard: "Out-of-equilibrium nanosystems: Principles and applications"


The function of nanodevices is often associated with their nonequilibrium properties such as electric conductance, reaction rates in catalysis, or energy transduction in thermoelectric converters or molecular motors. These properties are formulated in terms of nonequilibrium thermodynamics and the response relations between the rates and the affinities. In nanodevices, the nonlinear-response properties are no longer negligible in contrast to what happens at the macroscale. Moreover, thermal and molecular fluctuations become major features of the description of nanosystems. Recent advances and notably the fluctuation theorem provide a framework to understand how directionality emerges out of equilibrium, allowing information processing at the nanoscale as it is the case in biological systems.
