Typical two-dimensional atomic density and phase profiles of slow rotation for different inter-component interactions (β12 = 50 in the top two rows and β12 = 250 in the bottom two rows) and DDIs. The strengths of dipolar interaction are set as (a) εdd = 0, (b) εdd = 1, (c) εdd = 2, and (d) εdd = 4 for the top two rows, and (a) εdd = 0, (b) εdd = 2, (c) εdd = 3, and (d) εdd = 4 for the bottom two rows. Other parameters are set as Ω = 0.7 and θ = π/2.
