Título: Analytic solution of the Domain Wall non-equilibrium stationary state

Abstract: I'll consider the out-of-equilibrium dynamics generated by joining two domains with arbitrary opposite magnetisations. I'll focus in particular on the paradigmatic example of the XXZ spin chain and solve exactly the quench dynamics with a recent hydodynamics method suitable for integrable models. I'll show that the spin current can have a "no-where" continuous behavior and show that interactions always prevent the emergence of a Tracy-Widom distribution at the edges.
