Collective resonance fluorescence in small and dense atom clouds: Comparison between theory and experiment
S. D. Jenkins, J. Ruostekoski, J. Javanainen +5
We study the emergence of a collective optical response of a cold and dense Rb atomic cloud to a near-resonant low-intensity light when the atom number is gradually increase…
Optical resonance shifts in the fluorescence of thermal and cold atomic gases
S. D. Jenkins, J. Ruostekoski, J. Javanainen +4
We show that the resonance shifts in the fluorescence of a cold gas of rubidium atoms substantially differ from those of thermal atomic ensembles that obey the standard continuous…
Observation of suppression of light scattering induced by dipole-dipole interactions in a cold atomic ensemble
J. Pellegrino, R. Bourgain, S. Jennewein +4
We study the emergence of collective scattering in the presence of dipole-dipole interactions when we illuminate a cold cloud of rubidium atoms with a near-resonant and weak intens…
Direct measurement of the Wigner time-delay for the scattering of light by a single atom
R. Bourgain, J. Pellegrino, Y. R. P. Sortais +1
We have implemented the gedanken experiment of an individual atom scattering a wave packet of near-resonant light, and measured the associated Wigner time-delay as a function of th…
Study of light-assisted collisions between a few cold atoms in a microscopic dipole trap
A. Fuhrmanek, R. Bourgain, Y. R. P. Sortais +1
We study light-assisted collisions in an ensemble containing a small number (~3) of cold Rb87 atoms trapped in a microscopic dipole trap. Using our ability to operate with one atom…
