| Figure 10. Spectra under the OBC and the density profiles of the special modes. (g), (h), and (i) are the density profiles of the special modes corresponding to (a), (b), and (c) at a fixed t = 0.5. In (a) and (d), γ = 0.2; in (b) and (e), γ = 0.65; in (c) and (f), γ = 3. The other parameters are Δ = 2/3, t1 = 1, and N = 21. N is the number of lattice sites of one chain. The special modes modes are marked with prismatic pink. |
