Description

In this talk I consider transport in mesoscopic systems under the influence of time-varying driving forces, where fluctuation relations connect the statistics of pairs of time reversed evolutions of physical observables. I will discuss general functional fluctuation relations for current flow in mesoscopic quantum systems induced by time-varying forces. Successive measurement processes implied by this setup do not put the derivation of quantum fluctuation relations in jeopardy. While in many cases the fluctuation relation for a full time-dependent current profile may contain excessive information, a number of reduced relations can be given, and their application to mesoscopic transport will be discussed. Examples include the distribution of transmitted charge, where the derivation of a fluctuation relation requires the combined monitoring of the statistics of charge and work.
