(a) The ground state density profile of ϕ1, (b) the ground state density profile of ϕ2, (c) the comparison of ϕ1 (solid line) with the analytic solution (dashed line) of Eq. (15), and (d) the comparison of ϕ2 (solid line) with the analytic solution (dashed line) of Eq. (16). Here we take M = 0.4, g11 = g22 = 1000, g12 = g21 = 800, Ω = 0.5, r0 = 11, and V0 = 0.5.
