Fig. 1

a Scheme of the lattice with PBC along the a1 direction. The dashed red lines at the two ends of the strip mark the sites that are connected by PBC. b Bands of the Haldane model in a strip configuration with zigzag edges, with PBC along the a1 direction and Ny = 60 sites in the y (or a2) direction. The parameters are set as t1 = 1, t2 = 0.3, m = 0, ϕ = π/2.
