Description:
Author(s): Xiurong Zhang, Francesco Piazza, WeiDong Li, and Augusto Smerzi We study analytically the superfluid flow of a Bose-Einstein condensate in a ring geometry in the presence of a rotating barrier. We show that a phase transition breaking a parity symmetry among two topological phases occurs at a critical value of the height of the barrier. Furthermore, a discontinu… [Phys. Rev.
