Matter Wave Transport and Anderson Localization in Anisotropic 3D Disorder
arXiv:1112.2859 · doi:10.1209/0295-5075/99/50003
Abstract
We study quantum transport in anisotropic 3D disorder and show that non rotation invariant correlations can induce rich diffusion and localization properties. For instance, structured finite-range correlations can lead to the inversion of the transport anisotropy. Moreover, working beyond the self-consistent theory of localization, we include the disorder-induced shift of the energy states and show that it strongly affects the mobility edge. Implications to recent experiments are discussed.
