| Popis: |
We theoretically investigate a two-dimensional harmonically-trapped gas of identical atoms with Rashba spin-orbit coupling and no interatomic interactions. In analogy with the spin Hall effect in uniform space, the gas exhibits a spin Hall mode. In particular, in response to a displacement of the center-of-mass of the system, spin-dipole moment oscillations occur. We determine the properties of these oscillations exactly, and find that their amplitude strongly depends on the spin-orbit coupling strength and the quantum statistics of the particles. |
