ABSTRACT=We consider a harmonically trapped rotating spin-$1$ Bose-Einstein condensate with SU(3) spin-orbit coupling subject to a gradient magnetic field. The effects of SU(3) spin-orbit coupling, rotation, and gradient magnetic field on the ground state structure of the system are investigated in detailed. Our results show that the interplay among SU(3) spin-orbit coupling, rotation, and the gradient magnetic can results a variety of ground states, such as vortex ring, clover-type structure, and so on. The numerical results agree well with our variational analysis.
