In this paper, we study the modification of coherent scattering processes in dense ensembles. Using absorption imaging, we experimentally demonstrate that the absorption cross section in dense ^{87}Rb cold atom ensembles is reduced, with respect to t

International audience; We report on the use and qualification of the recently developed single-mode hybrid hollow-core photonic crystal fiber for a robust and long-life acetylene photonic micro-cell based optical frequency reference.

We study the long-range force arising from the absorption of non-saturating laser beams in a two-dimensional cloud of cold atoms. The force created by the lasers is at- tractive and similar to the usual Newtonian gravity along the beam. The cloud is

In two dimensions, a system of self-gravitating particles collapses and forms a singularity in finite time below a critical temperature $T_c$. We investigate experimentally a quasi two-dimensional cloud of cold neutral atoms in interaction with two p

Cold atom experiments require single frequency narrow linewidth lasers in order to address specific transitions. It is mandatory to lock the lasers to fixed references, because due to environmental fluctuations, drifts change the laser frequency outs

We consider the two dimensional motion of a particle into a confining potential, subjected to Brownian forces, associated with two different temperatures on the orthogonal directions. Exact solutions are obtained for an asymmetric harmonic potential
