5 Jul 2006 | | Subject: | Mesoscopic Systems and Quantum Hall Effect | | Abstract: | We propose an experimental scheme to observe spin Hall effects with cold atoms in a light induced gauge potential. Under an appropriate configuration, the cold atoms moving in a spatially varying laser field experience an effective spin-dependent gauge potential. Through numerical simulation, we demonstrate that such a gauge field leads to observable spin Hall currents under realistic conditions. We also discuss the quantum spin Hall state in an optical lattice. | | Source: | arXiv, cond-mat/0607127 | | Services: | Forum | Review | PDF | Favorites | |
