Title: Fluctuation Relations for Open Systems

Abstract:

The celebrated fluctuation relations (Crook's fluctuation theorem, 
Jarzinsky's identity, Gallavotti-Cohen symmetry etc.) express the 
time-irreversibility of an open system's evolution and link it to 
thermodynamic quantities such as entropy production, dissipated work 
etc. In a way, they provide stochastic formulations of the Second Law of 
thermodynamics. In this lecture I will provide the simplest possible 
derivation of fluctuation relations and discuss the possibility of 
generalizing them in the case where the observer has partial information 
about the system. I will also briefly touch on the formulation of 
fluctuation relations for quantum systems.
