Nonholonomy of order parameters and su(3) vortices in spin-1 Bose-Einstein condensates
arXiv:1804.05518 · doi:10.1103/PhysRevA.98.013607
Abstract
A generalized Mermin-Ho relation for a spin-1 BEC 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.
