Anomalous Levy diffusion in an optical lattice and ergodicity breaking — •Eric Lutz — Abteilung Quantenphysik, Universitaet Ulm, D-89069 Ulm

We investigate anomalous transport in an optical lattice from the point of view of statistical mechanics and establish an explicit correspondence between ergodicity breaking and the divergence of the moments of the power-law tail distributions describing the behavior of the system, both in momentum space and in time.
