Query: Phase-separated symmetry-breaking vortex-lattice in a binary
  Bose-Einstein condensate   We study spontaneous-symmetry-breaking circularly-asymmetric phase separation
of vortex lattices in a rapidly rotating harmonically-trapped
quasi-two-dimensional (quasi-2D) binary Bose-Einstein condensate (BEC) with
repulsive inter- and intra-species interactions. The phase separated vortex
lattices of the components appear in different regions of space with no overlap
between the vortices of the two components, which will permit an efficient
experimental observation of such vortices and accurate study of the effect of
atomic interaction on such vortex lattice. Such phase separation takes place
when the intra-species interaction energies of the two components are equal or
nearly equal with relatively strong inter-species repulsion. When the
intra-species energies are equal, the two phase-separated vortex lattices have
identical semicircular shapes with one being the parity conjugate of the other.
When the intra-species energies are nearly equal, the phase separation is also
complete but the vortex lattices have different shapes. We demonstrate our
claim with a numerical solution of the mean-field Gross-Pitaevskii equation for
a rapidly rotating quasi-2D binary BEC.
