Persistent currents in spinor condensates
arXiv:1210.4834 · doi:10.1103/PhysRevLett.110.025301
Abstract
We create and study persistent currents in a toroidal two-component Bose gas, consisting of Rb atoms in two different spin states. For a large spin-population imbalance we observe supercurrents persisting for over two minutes. However we find that the supercurrent is unstable for spin polarisation below a well defined critical value. We also investigate the role of phase coherence between the two spin components and show that only the magnitude of the spin-polarisation vector, rather than its orientation in spin space, is relevant for supercurrent stability.
