| contents | The interplay between many-body interactions and controlled dissipation provides a rich framework for exploring nonequilibrium quantum phases. In this work, we explore an open Dicke model including Rydberg-dressed interactions in a driven-dissipative cavity and unveil its unique nonequilibrium dynamics therein. We find that Rydberg-dressed interactions generate an additional critical coupling, which alters the stability of fixed points and hence determines fruitful dynamical phase transitions. Beyond the mean-field limit, we demonstrate that our system supports a superradiant continuous time crystal (CTC) phase, proving CTC can exist in an interacting spin-1/2 system. By bridging driven-dissipative quantum cavity and interacting atomic systems, our Rydberg-dressed Dicke system offers measurable signatures from the cavity emission photons, making it experimentally feasible as a versatile platform for exploring dynamical phase transitions and macroscopic temporal order in open quantum matter. |
