Morphological Superfluid in a Nonmagnetic Spin-2 Bose-Einstein Condensate

Research output: Contribution to journalArticle


The two known mechanisms for superflow are the gradient of the U(1) phase and the spin-orbit-gauge symmetry. We find the third mechanism, namely a spatial variation of the order-parameter morphology protected by a hidden su(2) symmetry in a nonmagnetic spin-2 Bose-Einstein condensate. Possible experimental situations are also discussed.
