Light transport within a dense atomic cloud

When the density of a cold atomic cloud is comparable to or higher than 1/λ³, where λ is the wavelength of the resonant scattered light, the light transport properties are affected by short-range dipole-dipole dephasing of the atomic coherences. This has been experimentally studied with rubidium atoms in several geometries, either 2D or at optical tweezers, and discrepancies were observed when those results were compared to theory. The J = 0 to J = 1 strong transition of bosonic Strontium presents a non-degenerated fundamental level, which greatly simplifies the theoretical model and makes the system formally equivalent to classical dipoles in the linear regime. I will discuss the effects of the short-range dipole-dipole dephasing on several observables, and I will show preliminary experimental results of the coherent transmission of our atomic cloud.
