The importance of large deviations in non-equilibrium systems

by Bernard Derrida (Collège de France and Ecole Normale Supérieure)

Several symmetries of non equilibrium systems such as fluctuation theorems or work relations can be formulated in terms of large deviation functions. After a brief review of these general properties the talk will focus on a series of results obtained over the last decade on the large deviation functions of diffusive systems. It will also list a number of open issues for diffusive and non diffusive systems.
