英文摘要: When a Bosa Einstein condensate is set to rotate, superfluid vortices will be formed, which finally condense. into a vortex lattice as. the rotation frequency further increases. We show that the dipole-dipole interaction's renormalize the short-range interaction strength and result in a distinction between interactions of parallel-polarized atoms and interactions of antiparallel-polarized atoms. This effect may lead to a spontaneous breakdown of the rapidly rotating Bose condensate into a novel anti-ferromagnetic-like vortex lattice. The upward-polarized Bose condensate forms a vortex lattice, which is staggered against a down ward-polarized vortex lattice. A phase diagram related to the coupling strength is obtained.
