Non-Gaussian correlations in the steady-state of driven-dissipative clouds of two-level atoms
Giovanni Ferioli, Sara Pancaldi, Antoine Glicenstein +3
We report experimental measurements of the second-order coherence function of the light emitted by a laser-driven dense ensemble of Rb atoms. We observe a clea…

Emergence of second-order coherence in the superradiant emission from a free-space atomic ensemble
Giovanni Ferioli, Igor Ferrier-Barbut, Antoine Browaeys
We investigate the evolution of the second-order temporal coherence during the emission of a superradiant burst by an elongated cloud of cold Rb atoms in free space. To do so, we m…

Driven-dissipative phase separation in free-space atomic ensembles
Daniel Goncalves, Lisa Bombieri, Giovanni Ferioli +5
The driven Dicke model, wherein an ensemble of atoms is driven by an external field and undergoes collective spontaneous emission due to coupling to a leaky cavity mode, is a parad…
