Title : CLT for NESS

Abstract : Non-equilibrium stationary states (NESS) are ubiquitous in nature, but not well understood from a mathematical point of view. The main features of NESS is the presence of non-trivial currents, which generate long-range correlations in the system. Modeling physical systems by Markov chains, one can restate questions about NESS as the description of invariant measures for non-reversible Markov chains. This opens the way to describe NESS by probabilistic methods. However, basic questions for non-reversible Markov chains, like for example mixing times or quantitative CLTs are not been answered in great generality. Our first talk will introduce NESS with some examples, and it will introduce general and fairly elementary methodology for Markov chains that we believe is well suited to the study of non-reversible Markov chains. The second talk will describe some recent results about the description of NESS for driven-diffusive systems.
