Discrete Time Crystals in the Absence of Manifest Symmetries or Disorder in Open Quantum Systems
Discrete Time Crystals in the Absence of Manifest Symmetries or Disorder in Open Quantum Systems
We establish a link between metastability and a discrete time-crystalline phase in a periodically driven open quantum system. The mechanism we highlight requires neither the system to display any microscopic symmetry nor the presence of disorder, but relies instead on the emergence of a metastable regime. We investigate this in …
