Fig. 8: Normalized localization length Λ as functions of ∣ϕpq∣ with \(\tilde{t}=\frac{\pi v}{2a},W=3v/a,{E}_{F}=0\), and various transversal sizes L.

The used longitudinal size is M = 107 and the precision (σΛ/Λ) has reached 2%. The point with ∣ϕpq∣ = 3π/4 corresponds to the middle of Fig. 2f. The point with ∣ϕpq∣ = π recovers TRS and is localized under any finite on-site disorders.
