Article Synopsis
- An extensive study of elastic scattering time τ_{s} of matter waves in optical disordered potentials was conducted, utilizing experimental measurements and numerical simulations.
- The research examines τ_{s} across a wide range of scattering regimes and highlights the significant impact of disorder statistics, particularly regarding the Ioffe-Regel-like criterion kl_{s}∼1.
- The findings provide important insights that link experimental studies of complex transport phenomena, like Anderson localization, to underlying microscopic theories.
We report on the measurement of the spectral functions of noninteracting ultracold atoms in a three-dimensional disordered potential resulting from an optical speckle field. Varying the disorder strength by 2 orders of magnitude, we observe the crossover from the "quantum" perturbative regime of low disorder to the "classical" regime at higher disorder strength, and find an excellent agreement with numerical simulations. The method relies on the use of state-dependent disorder and the controlled transfer of atoms to create well-defined energy states.
