Coreless vortex formation in a spinor Bose-Einstein condensate

arXiv:cond-mat/0212539 · doi:10.1103/PhysRevLett.90.140403

Abstract

Coreless vortices were phase-imprinted in a spinor Bose-Einstein condensate. The three-component order parameter of F=1 sodium condensates held in a Ioffe-Pritchard magnetic trap was manipulated by adiabatically reducing the magnetic bias field along the trap axis to zero. This distributed the condensate population across its three spin states and created a spin texture. Each spin state acquired a different phase winding which caused the spin components to separate radially.
