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.
Using an atomic quasiperiodic kicked rotor -- equivalent to a two-dimensional
Anderson-like model -- we experimentally study Anderson localization
in dimension 2 and we observe localized wave function dynamics. We
also show that the localization length depends exponentially on the
disorder strength and anisotropy and is in quantitative
agreement with the predictions of the self-consistent theory for the
2D Anderson localization.
