An effective quasi-one-dimensional description of a spin-1 atomic condensate

Abstract

Within the mean field theory we extend the effective quasi-1D non-polynomial 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.
