(color online) (a) The quasi-particle excitation spectrum E_k,− (solid lines) and quasi-hole excitation spectrum (dashed lines) with k_x = 0. For the green lines, h = 0.37E_F; for the red lines, h = 0.51E_F; for the blue lines, h = 0.54E_F. (b) The energy gap E_gap as a function of h. Other parameters are: μ_r/E_F = 0.2, αk_F/E_F = 0.7, v = 0.053, E_b = 0.35E_F.
