Fig. 3: Emerging phase diagram.
From: Emerging topological bound states in Haldane model zigzag nanoribbons
Phase diagram of the model as a function of the staggered on-site potential m for different widths: (a) Ny = 4; (b) Ny = 6; (c) Ny = 8; (d) Ny = 10. The model parameters are set to t1 = 1, t2 = 0.3 and ϕ = π/2. The regions of the parameter space where a star is drawn, are those expected to be topologically non trivial. The yellow and red dots in (d) mark the two phases inspected in Fig. 6.
