## Elastic Scattering Time of Matter Waves in Disordered Potentials

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 …

## Coherent Backscattering of Ultracold Atoms

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 …

## Three-dimensional localization of ultracold atoms in an optical disordered potential

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, …
