The typical two-dimensional atomic density and phase profiles of the slow rotation case for different inter-component interactions (β₁₂ = 50 for the top two rows and β₁₂ = 250 for the bottom two rows) and DDIs. The strengths of dipolar interaction are set as (a) ε_dd = 0, (b) ε_dd = 1, (c) ε_dd = 2, and (d) ε_dd = 4 for the top two rows, and (a) ε_dd = 0, (b) ε_dd = 0.3, (c) ε_dd = 2, and (d) ε_dd = 4 for the bottom two rows. Other parameters are set as Ω = 2.5 and θ = π/2.
