Discrete time crystals in many-body quantum chaos
Discrete time crystals in many-body quantum chaos
Discrete time crystals (DTCs) are phases of matter characterized by the presence of an observable evolving with $nT$ periodicity under a $T$-periodic Hamiltonian, where $n>1$ is an integer insensitive to small parameter variations. In particular, DTCs with $n=2$ have been extensively studied in periodically quenched and kicked spin systems in …
