    • A similar situation was reported in J.J. García-Ripoll et al., Phys. Rev. A 66, 021602(R) (2002), where special attention was paid to the effects of the phase separation of binary BECs with vorticity under slow rotation.

    • note
    • These vortex and antivortex have circulations of the same sign in the respective phase spaces, but they are out of phase in the relative phase space, in contrast to a conventional vortex-antivortex pair.

    • note
    • If the molecule is polarized along the y axis, the texture forms a "circular-hyperbolic" pair. Those two configurations are different just in their orientation of the molecular polarization, and can therefore continuously transform into each other.

    • note
    • 2)/√2, the nonaxisymmetric structure in Fig. 1 is transformed to the axisymmetric vortex state. Here, the vortex core of the " + " component is filled with "-" particles. Then, the internal coupling is just the chemical potential difference between the "+" and "-" components. As one increases λ the number of " -" particles drops, and the vortex cores eventually become empty [corresponding to the bottom of Fig. 2(a)].

    • note
    • The rotation also produces an energy minimum without the internal coupling, which is irrelevant to the binding due to the domain wall of the relative phase.
