Abstract

The scattering of light by dilute cold atomic clouds is a long-range problem by nature, as light induces an effective 1/r interaction between the atomic dipoles. The relative absence of decoherence allows
for classical and quantum correlations to be preserved over long distances, which makes cooperative phenomena such as superradiance or subradiance possible in dilute clouds.

In this context, I will present recent results on optical coherences of large cold atomic clouds, probing both classical and quantum signatures of the coupling between the atoms. The possibility of optically bind pairs of cold atoms will also be discussed.

Looking forward to seeing many of you at the seminar!
