We report on the direct measurement of the elastic scattering time $\tau_S$ of ultracold atoms propagating in optical disordered potentials. By exploring this fundamental quantity over a large range of experimental parameters, we observe variations …
We report on the direct observation of coherent backscattering (CBS) of ultracold atoms in a quasi-two- dimensional configuration. Launching atoms with a well-defined momentum in a laser speckle disordered potential, we follow the progressive build …
In disordered media, quantum interference effects are expected to induce complete suppression of electron conduction. The phenomenon, known as Anderson localization, has a counterpart with classical waves that has been observed in acoustics, …
