The approach to equilibrium is exceedingly complex and c an be probed in a myriad of ways. In this seminar\, we will address this q uestion through the lens of entanglement asymmetry. This is a recently int roduced\, information-based observable that quantifies how much a symmetry is broken within a subsystem. As an illustration\, we will consider the c ase where a symmetry explicitly broken by the initial state is dynamically restored. Remarkably\, we find that the more the symmetry is initially br oken\, the faster it is restored\, a quantum analogue of the Mpemba effect . We will further discuss the conditions under which this phenomenon occur s and present direct experimental evidence from a trapped-ion quantum simu lator.
