Dicke time crystals in driven-dissipative quantum many-body systems
Dicke time crystals in driven-dissipative quantum many-body systems
The Dicke model—a paradigmatic example of superradiance in quantum optics—describes an ensemble of atoms which are collectively coupled to a leaky cavity mode. As a result of the cooperative nature of these interactions, the system's dynamics is captured by the behavior of a single mean-field, collective spin. In this mean-field …
