Strong-field coherent backscattering of light in ultracold atomic 85Rb

We report experimental observations of polarization-dependent coherence loss occurring in strong-field multiple scattering of light in ultracold atomic 85Rb. A measure of coherence in multiple light scattering is the degree of contrast of the coherent backscattering enhancement from the vapour. For resonance saturation parameters up to 9, we see light-polarization-dependent modification of the backscattering enhancement, suggesting that inelastic atomic light scattering and dynamic atomic magnetization may play important roles in the multiple scattering process for 85Rb.We report experimental observations of polarization-dependent coherence loss occurring in strong-field multiple scattering of light in ultracold atomic 85Rb.

Observation of Light-Induced Dipole-Dipole Forces in Ultracold Atomic Gases

Light-matter interaction is well understood on the single-atom level and routinely used to manipulate atomic gases.However, in denser ensembles, collective effects emerge that are caused by light-induced dipole-dipole interactions and multiple photon scattering.Here, we report on the observation of a mechanical deformation of a cloud of ultracold 87 Rb atoms due to the collective interplay of the atoms and a homogenous light field.This collective light scattering results in a self-confining potential with interesting features: It exhibits nonlocal properties, is attractive for both red-and blue-detuned light fields, and induces a remarkably strong force that depends on the gradient of the atomic density.Our experimental observations are discussed in the framework of a theoretical model based on a local-field approach for the light scattered by the atomic cloud.Our study provides a new angle on light propagation in highdensity ensembles and expands the range of tools available for tailoring interactions in ultracold atomic gases.Light-matter interaction is well understood on the single-atom level and routinely used to manipulate atomic gases.However, in denser ensembles, collective effects emerge that are caused by light-induced dipole-dipole interactions and multiple photon scattering.Here, we report on the observation of a mechanical deformation of a cloud of ultracold 87 Rb atoms due to the collective interplay of the atoms and a homogenous light field.This collective light scattering results in a self-confining potential with interesting features: It exhibits nonlocal properties, is attractive for both red-and blue-detuned light fields, and induces a remarkably strong force that depends on the gradient of the atomic density.Our experimental observations are discussed in the framework of a theoretical model based on a local-field approach for the light scattered by the atomic cloud.Our study provides a new angle on light propagation in highdensity ensembles and expands the range of tools available for tailoring interactions in ultracold atomic gases.
