Phys. Rev. Lett. 91, 150402 (2003) [4 pages]Normal-Superfluid Interaction Dynamics in a Spinor Bose GasReceived 20 June 2003; published 7 October 2003 Coherent behavior of spinor Bose-Einstein condensates is studied in the presence of a significant uncondensed (normal) component. Normal-superfluid exchange scattering leads to near-perfect local alignment between the spin fields of the two components. We observe that, through this spin locking, spin-domain formation in the condensate is vastly accelerated as the spin populations in the condensate are entrained by large-amplitude spin waves in the normal component. © 2003 The American Physical Society URL:
