In our previous paper [T. Kashimura, S. Tsuchiya, and Y. Ohashi, Phys. Rev. A {\\bf 82}, 033617 (2010)], we showed that excess atoms ($\\Delta N=N_\\uparrow-N_\\downarrow$) localized around a potential barrier embedded in the system induces the $\\pi$-phase at T=0, where the phase of superfluid order parameter differ by $\\pi$ across the junction.
