16 Jun 2005 | | Subject: | Disordered Systems and Neural Networks | cond-mat.dis-nn | | Abstract: | We study transport of interacting electrons in a low-dimensional disordered system at low temperature $T$. In view of localization by disorder, the conductivity $sigma(T)$ may only be non-zero due to electron-electron scattering. For weak interactions, the weak-localization regime crosses over with lowering $T$ into a dephasing-induced "power-law hopping". As $T$ is further decreased, the Anderson localization in Fock space crucially affects $sigma(T)$, inducing a transition at $T=T_c$, so that $sigma(T | | Source: | arXiv, cond-mat/0506411 | | Services: | Forum | Review | PDF | Favorites | |
