Title:
Effective theory of entanglement dynamics
Speaker:
Abstract:
Following the time evolution of entanglement entropy can provide insight into the chaotic process of thermalization in a quench in an isolated quantum system. In this talk, based on a diverse set of examples I propose that there are two universality classes of entropy dynamics in the limit of large entangling regions and late times: the quasiparticle model describing integrable theories and the membrane theory applicable to chaotic systems. The membrane theory reveals connections between entanglement dynamics and chaotic operator growth.
