a shows a quasi-2D lattice respecting group P4/nmm. The green and red balls label the two sublattices. The orange and brown dashed lines indicate the different edges considered in the text. The black dashed arrows represent a bending process from the (10) edge to the [11] and \([1\overline{1}]\) edges. b presents the bands obtained from Eq. (4), with G, X, M representing (0, 0), (π, 0), (π, π) in the Brillouin zone, respectively, with the other parameters set to be \(\{t,\, {t}^{{\prime} },\, \lambda \}=\{-1.0,0.8,0.5\}\). The blue dashed line in (b) represents the chemical potential considered in the text.
