Fourier imaging of collective spontaneous emission modes in superradiant cold atomic clouds
Adrien Gavalda, Guillaume Tremblier, Martin Poitrinal +3
We measure the spatial pattern associated with the superradiant emission from a cloud of cold 87Rb atoms using Fourier imaging. We observe a highly directional, ring-shaped emissio…
Narrowline cooling of dysprosium atoms in an optical tweezer array
Giulio Biagioni, Britton Hofer, Nathan Bonvalet +3
We perform narrowline cooling of single dysprosium atoms trapped in a 1D optical tweezers array, employing the narrow single-photon transition at 741 nm. At the trapping wavelength…
Connected correlations in cold atom experiments
Thomas Chalopin, Igor Ferrier-Barbut, Thierry Lahaye +2
The recent development of single-atom-resolved probes has made full counting statistics measurements accessible in quantum gas experiments. This capability provides access to high-…
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…
