摘要：

This talk will introduce our recent joint theory and experiment work on non-stationary dynamics in Rydberg atom ensembles. We focus on nonequilibrium dynamics of an atom ensemble where Rydberg atom interactions, laser coupling and dissipation compete. A series of stationary phases, including uniform, antiferromagnetic, oscillatory, and bistable phases are obtained. Recent experiments have interpretated the oscillatory phase as synchronization, or dissipative time crystal. However the oscillation phase is not possible in general due to complicated interactions between the atoms. We show that the oscillation is due to the formation of Rydberg excitation clusters, where atoms in a cluster are dynamically active. The quasi-regular structure of the active atoms allows the long-term oscillations.
