Title:Two facets of one-dimensional stochastic models

Abstract: I start by a summary about the interplay between the quantum integrability and the studies of one-dimensional stochastic processes as the Asymmetric Simple Exclusion Process (ASEP). Then, the matrix ansatz, which is the usual method to compute exactly the stationary state for stochastic processes, is explained and generalized to get the stationary state for the multi-species exclusion process. Finally, I discuss the use of the Bethe ansatz in this context and the surprising connection with the Lee-Yang zeroes.
