Single-atom resolved collective spectroscopy of a one-dimensional atomic array
Britton Hofer, Damien Bloch, Giulio Biagioni +3
Ordered atomic arrays feature an enhanced collective optical response compared to random atomic ensembles due to constructive interference in resonant dipole-dipole interactions. O…
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…
Anisotropic polarizability of Dy at 532 nm on the intercombination transition
Damien Bloch, Britton Hofer, Sam Roberto Cohen +3
We report experimental measurements of the dynamical polarizability of dysprosium, at a wavelength of 532 nm. We measure all three components (scalar, vector, tensor) of the anisot…
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…
