Experimental observation of two-dimensional Anderson localization with the atomic kicked rotor

Résumé

Dimension 2 is expected to be the lower critical dimension for Anderson localization in a time-reversal-invariant disordered quantum system: the dynamics is generically localized in dimension lower than 2, while it presents a transition from a diffusive regime at weak disorder to a localized regime at strong disorder in dimension larger than 2. We use an atomic quasiperiodically kicked rotor – equivalent to a two-dimensional Anderson-like model – to experimentally study Anderson localization in dimension 2. We observe a localized dynamics with a localization length depending exponentially on the disorder strength and show that a self-consistent theory of localization quantitatively predicts the localization length.
