The pi spin-glass / time crystal phase
Curt von Keyserlingk, Princeton & KITP

Recent work shows that there is a sharp notion of .phase of matter. in periodically driven many-body localised systems. In this talk I give a pedagogical review of perhaps the simplest such driven phase of matter, known as the pi spin-glass/ time crystal. A key feature of this phase is that in the thermodynamic limit, for fairly generic initial states, generic local observable show persistent oscillations at late times commensurate with the driving period.
