Interacting many-body quantum systems often exhibit chaotic dynamics that rapidly ``scramble’’ quantum information and lead to highly entangled states whose local properties are thermal and classical. At long times, most many-body quantum systems reach thermal equilibrium on their own. In this talk, I will discuss recently discovered exceptions to this rule, and focus on systems in which thermalization can be prevented either by many-body localization, integrability or by local projective measurements. I will discuss the new types of non-equilibrium phases and phase transitions that can arise in such systems, with an emphasis on the emergence of universality far from thermal equilibrium.
