Spin Texture Formation Induced by Weak Magnetic Dipole Interaction in a Bose-Einstein Condensate : Magnetic Gas of Ultracold Rb Atoms(Research)

Abstract

We observed the spin texture formation and the spatial modulation of the longitudinal magnetization in a spin-2 ^<87>Rb Bose-Einstein condensate. The observed results are compared with numerical simulations of the Gross-Pitaevskii equation, which are the effects due to the magnetic dipole-dipole interaction. These results show that the magnetic dipole-dipole interaction has significant effects even on spinor condensates of alkali metal atoms.
