Philippe Sabella-Garnier  - Thermalization in integrable field theories 

Abstract: Perturbations of states in integrable or free field theories are not expected to thermalize due to the constraints imposed by the existence of an extensive number of conserved charges. In this talk, I will show that this is indeed the case when the perturbation probing the system satisfies a simple no-go condition. I will present examples of how this condition applies in 2D CFTs, in higher-dimensional free field theories, and in the transverse field Ising model. At the same time, I will also show how perturbations that do not obey this no-go condition easily thermalize in all of these models.

This event is part of a regular series of meetings sponsored by Delta ITP with the objective of bringing together the theoretical physics communities in Amsterdam, Leiden, Utrecht and our sister nodes Groningen, Brussels (ULB and VUB) and Leuven. The topic of this meeting is holography and its applications to different physical systems. We encourage researchers from different areas in theoretical physics to participate!
