Abstract

A generalized Mermin-Ho relation for a spin-1 Bose-Einstein condensate is derived, which is applicable to vortices regardless of the symmetry and spin polarization of the order parameter. The obtained relation implies an su(3) mass-current circulation and two classes of vortices corresponding to two different su(2) subalgebras.

Circulation condition of the two-component Bose-Einstein condensate

JiaDJ, DuanYS, LeeX

A new circulation condition which appears as a generalization of Mermin-Ho relation is presented for two-component spin-1/2 Bose-Einstein condensates as a topological constrain of the superfluid velocity due to SU(2) symmetry of the internal states. The possibility of creating fractional vortices in the condensate is discussed. (C) 2001 Elsevier Science B.V. All rights reserved.

Using decomposition of the SU(2) gauge field in terms of unit vector field, we have discussed circulation condition of the spin-1/2 Bose-Einstein dendensate. For the two-component Bose-Einstein condensate,the SU/(2) symmetry of the internal states leads to a generalization of Mermin-Ho relation as a topological constrain of the superfluid velocity.

su(N) Mermin-Ho relation

Emi Yukawa

The Mermin-Ho relation expresses the vorticity of a coreless su(2) vortex in terms of the spin-1 or l vector which characterizes fully polarized superfluid textures. We generalize it to an su(N) vortex which is applicable to arbitrarily polarized superfluid textures with higher spin or angular momentum. The obtained relation is expressed in terms of the mean-field generators and their structure factors.
