Enhanced transport when Anderson localization is destroyed
arXiv:1110.3024 · doi:10.1088/1367-2630/14/4/043047
Abstract
We investigate the anomalous transport in optically-induced potentials that are random in both space and time. We find that the time variation destroys Anderson localization, replacing it by transport that is faster than diffusion, which in some cases can be even faster than ballistic. We relate this phenomenon to Chirikov's theory of overlapping resonances, and find radical differences between the anomalously-enhanced transport in one-dimensional and two-dimensional systems.
