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.
