Initial condensate densities in harmonic trap (not shown) with a stationary soliton being located at x₀ = −30ξ, length unit being ξ=ℏ/μ1m1 . Corresponding unit in the following pictures is the same as in this picture. When dark solitons are not considered, density distribution of two BECs (short as BEC 1 and BEC 2) comes from imaginary-time propagation.
