Typical vortex structures of a two-component nondipolar BEC.

Here the upper plots [(a1)-(f1)] show the densities of either one component of the system (the marked dots denote the locations of the vortices) and the lower plots [(a2)-(f2)] indicate the corresponding phases. The aspect ratio of the potential λ = 100 and the contact interactions are fixed as g = 100, g₁₂ = 150. The rotational frequencies are set as (a) Ω = 0.54, (b) Ω = 0.55, (c) Ω = 0.68, (d) Ω = 0.7, (e) Ω = 0.8 and (f) Ω = 0.9, respectively. Note that, without dipolar interaction, these two components act like one component condensate, hence we only plot one component, either 1 or 2. The field of view is 6.4 × 6.4 in units of a₀.
