(color online) The contour lines of the excitation spectra E_k,+ (left) and E_k,− (right) in k_x-k_y plane. The local chemical potential μ_r/E_F = 0.8, the SOC strength αk_F/E_F = 0.8, h/E_F = 0.36, E_b = 0.41E_F. Other parameters are given as: For panels (a1) and (b1), v = 0.3; For panels (a2) and (b2), v = 0.35; For panels (a3) and (b3), v = 0.45; For panels(a4) and (b4), v = 0.5.
