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…
Directional superradiance in a driven ultracold atomic gas in free-space
Sanaa Agarwal, Edwin Chaparro, Diego Barberena +6
Ultra-cold atomic systems are among the most promising platforms that have the potential to shed light on the complex behavior of many-body quantum systems. One prominent example i…
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…
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 clear…
A non-equilibrium superradiant phase transition in free space
Giovanni Ferioli, Antoine Glicenstein, Igor Ferrier-Barbut +1
A class of systems exists in which dissipation, external drive and interactions compete and give rise to non equilibrium phases that would not exist without the drive. There, phase…
From superradiance to subradiance: exploring the many-body Dicke ladder
Antoine Glicenstein, Giovanni Ferioli, Antoine Browaeys +1
We report a time-resolved study of collective emission in dense ensembles of two-level atoms. We compare, on the same sample, the build-up of superradiance and subradiance from the…
