Floquet heating, prethermalization and time crystals

Shaking a quantum system periodically can create phases impossible in equilibrium, such as a time crystal, which responds at a multiple of the driving period. The drive also adds energy, and the system eventually heats to a featureless state unless something prevents it.

Why it matters

Periodic driving is a main experimental tool for engineering quantum matter, and heating sets how long engineered phases last.
