Large deviations in systems far from equilibrium
Studies of non-equilibrium fluctuations have held a center stage during the past few decades of the development of non-equilibrium statistical mechanics. Macroscopic fluctuations display some universal behaviour, quantified by large deviation functions.
In this talk, we describe a few results for non-equilibrium large deviations. In particular, we shall use techniques of integrable probabilities to derive an exact formula for the distribution of a tracer particle in the symmetric exclusion process, thus answering a problem that had eluded solution for decades.
Joint work with Takashi Imamura (Chiba) and Tomohiro Sasamoto (Tokyo).
