Subradiance and superradiance-to-subradiance transition in dilute atomic clouds

Abstract

The authors experimentally demonstrate a transition from superradiance to subradiance in a dilute cloud of ultracold Rb atoms and in the regime of strong excitation. They also show that, in this regime, the subradiant time scales depend on the excitation fraction of the cloud, i.e., on the intensity of the excitation pulse.
