Phys. Rev. A 71, 025603 (2005) [4 pages]An effective quasi-one-dimensional description of a spin-1 atomic condensateReceived 9 October 2004; published 24 February 2005 Within the mean field theory we extend the effective quasi-one-dimensional nonpolynomial Schrödinger equation (NPSE) approach to the description of a spin-1 atomic condensate in a tight radial confinement geometry for both weak and strong atom-atom interactions. Detailed comparisons with full time-dependent 3D numerical simulations show excellent agreement as in the case of a single component scalar condensate, demonstrating our result as an efficient and effective tool for the understanding of spin-1 condensate dynamics observed in several recent experiments. © 2005 The American Physical Society URL:
