We follow the evolution with sample thickness, of intensity statistics for localized light transmitted through layered media in a crossover from one to three dimensions occasioned by transverse disorder. The probability distribution of intensity changes from one dimensional to a mixture of a mesoscopic function of a single parameter, the "statistical conductance," and a distribution of intensity for Gaussian waves. This suggests that the change to a universal statistics beyond 1D is associated with the topological change in the spatial field distribution.

We review recent theoretical and experimental progresses in the coherent multiple scattering of weakly interacting disordered Bose gases. These systems have allowed, in the recent years, a characterization of weak and strong localization phenomena in disorder at an unprecedented level of control. In this paper, we first discuss the main physical concepts and recent experimental achievements associated with a few emblematic "mesoscopic" effects in disorder like coherent back scattering, coherent forward scattering or mesoscopic echos, focusing on the context of out-of-equilibrium cold-atom setu…
