I first show that the directed paths taken by the transport in the strongly localized regime are pinned by disorder and perform avalanches when a parameter like the energy is varied. I determine the roughness exponent $\\zeta=2/3$ characterizing the wandering of these paths and find that it is the same as that of the directed polymer problem. Finally, I characterize the disorder chaos property: Two replicas with infinitesimally perturbed disorder configurations have their conductance correlation which vanishes at the thermodynamic limit. Chaos is the result of the interplay between two distinct mechanisms: a spin glass chaos effect at strong disorder characteristic of directed polymer physics and an interference effect at weak disorder characteristic of universal conductance fluctuations.", "revisions": [ { "version": "v1", "updated": "2018-09-07T07:25:02.000Z" } ], "analyses": { "keywords": [ "glassy properties", "anderson localization", "avalanches", "spin glass chaos effect", "disorder chaos property" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable" } } }
