摘要：
By driving a Bose-Einstein condensate trapped in a single-mode high-Q optical resonator and coupled to a classical transverse running-wave field above a Dicke-like superradiant phase transition, the resulting cavity field-induced spin-orbit coupling leads to a band structure with doubly degenerate ground states. We show theoretically that the effective bosonic mode defined by interstate hopping can be entangled with the cavity field via the combined effect of spin-orbit coupling and dissipation.
