Abstract:
We analyze quasiperiodically driven quantum systems that can be mapped exactly to periodically driven ones and find Floquet time spirals in analogy with spatially incommensurate spiral magnetic states. Generalizing the mechanism to many-body systems, we discover that a form of discrete-time translation symmetry breaking can also occur in quasiperiodically driven systems. We construct a discrete-time quasicrystal stabilized by many-body localization. Crucially, it persists also under perturbation...     »
