Description

Entanglement evolution represents nowadays an important theoretical diagnostic to detect whether a quantum system out-of-equilibrium can eventually relax toward a stationary state at late times.
In this talk, I will introduce the main ideas and motivations beyond the study of entanglement dynamics in many-body systems by analyzing a paradigmatic model of statistical physics: the Ising spin chain.
In particular, I will review classic results such as the linear growth of the entanglement entropies and its link with thermalization. Eventually, I will discuss some new developments that were recently obtained in collaboration with O. Castro Alvaredo, Mate Lencses, and  Istvan M. Szecseny.
