Synchronization of two ensembles of atoms
Physical review letters, 2014•APS
We propose a system for observing the correlated phase dynamics of two mesoscopic
ensembles of atoms through their collective coupling to an optical cavity. We find a
dynamical quantum phase transition induced by pump noise and cavity output coupling. The
spectral properties of the superradiant light emitted from the cavity show that at a critical
pump rate the system undergoes a transition from the behavior of two independent
oscillators to the phase locking that is the signature of quantum synchronization.
