Spin Hall effects for cold atoms in a light-induced gauge potential.
نویسندگان
چکیده
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.

متن کاملGeneralized Stern-Gerlach effect for chiral molecules.
The Stern-Gerlach effect is well known as spin-dependent splitting of a beam of atoms with magnetic moments by a magnetic-field gradient. Here, we show that an induced gauge potential may lead to a similar effect for chiral molecules. In the presence of three inhomogeneous light fields, the center of mass of a three-level chiral molecule is subject to an optically induced gauge potential, and t...
متن کاملSpin-orbit coupling and Berry phase with ultracold atoms in 2D optical lattices.
We show how spin-orbit coupling and Berry phase can appear in two-dimensional optical lattices by coupling atoms' internal degrees of freedom to radiation. The Rashba Hamiltonian, a standard description of spin-orbit coupling for two-dimensional electrons, is obtained for the atoms under certain circumstances. We discuss the possibility of observing associated phenomena, such as the anomalous H...
متن کاملEffects of an optically induced non-Abelian gauge field in cold atoms
We show that N−1 degenerate dark states can be generated by coupling N-fold degenerate ground states and a common excited state with N laser fields. Interferences between light waves with different frequencies can produce laser fields with time-dependent amplitudes, which can induce not only U N non-Abelian vector fields but also the scalar ones for the adiabatic motion of atoms in such laser f...
متن کاملHaldane quantum Hall effect for light in a dynamically modulated array of resonators
Topological insulators have attracted abundant attention for a variety of reasons—notably, the possibility for lossless energy transport through edge states “protected” against disorder. Topological effects such as the quantum Hall state can be induced through a gauge field, which is, however, hard to create in practice, especially for charge-neutral particles. One way to induce an effective ga...
