Long-range gravitational-like interaction in a neutral atomic cold gas
Maryvonne Chalony, J. Barre, B. Marcos +2
A quasi-resonant laser induces a long-range attractive force within a cloud of cold atoms. We take advantage of this force to build in the laboratory a system of particles with a o…

Doppler cooling to the Quantum limit
Maryvonne Chalony, Anders Kastberg, Bruce Klappauf +1
Doppler cooling on a narrow transition is limited by the noise of single scattering events. It shows novel features, which are in sharp contrast with cooling on a broad transition,…

Coherent flash of light emitted by a cold atomic cloud
Maryvonne Chalony, Romain Pierrat, Dominique Delande +1
When a resonant laser sent on an optically thick cold atomic cloud is abruptly switched off, a coherent flash of light is emitted in the forward direction. This transient phenomeno…
