Atomic number fluctuations in a falling cold atom cloud
We evaluate the effective number of atoms in experiments where a probe laser beam with a Gaussian transverse profile passes through an atomic medium consisting in a cold atom cloud released from a magnetooptical trap. Considering the case where the initial distribution is a Gaussian function of position and of velocity, we give a quantitative description of the temporal variation of the effecti...
متن کاملSlow diffusion of light in a cold atomic cloud.
We study the diffusive propagation of multiply scattered light in an optically thick cloud of cold rubidium atoms illuminated by a quasiresonant laser beam. In the vicinity of a sharp atomic resonance, the energy transport velocity of the scattered light is almost 5 orders of magnitude smaller than the vacuum speed of light, reducing strongly the diffusion constant. We verify the theoretical pr...

متن کاملLarge Faraday rotation of resonant light in a cold atomic cloud
During the past 2 yr, we have been theoretically and experimentally investigating coherent backscattering ~CBS! of near-resonant light in a sample of cold rubidium atoms @1–3#. CBS is an interference effect in the multiple scattering regime of propagation inside random media, yielding an enhancement of the backscattered light intensity @4#. This interference is very robust and can be destroyed ...
متن کاملKibble-Zurek Mechanism in the Self-Organization of a Cold Atomic Cloud.
When applying two counterpropagating laser beams to a cold cloud of rubidium atoms, we observe the spontaneous formation of intensity patterns associated with a spatial structuration of the atomic spins. We study the average number of defects in these patterns as a function of the sweep time employed to cross the instability threshold. We observe a power-law decrease of the number of defects wi...
