a–c Evolution of the middle two bands with \(\tilde{t}\). d Normalized localization length Λ as functions of \(\tilde{t}\) with W = 1.5v/a, EF = 0 and various transversal sizes L. The used longitudinal size is M = 107 and the precision (σΛ/Λ) has reached 2%. e The phase diagram in \(\tilde{t}-W\) plane with EF = 0, where the green region represents the critical metal phase enclosed by the localized phase. Note that \({H}_{8B}^{{\prime} }\) in the clean limit has an additional chiral symmetry which fixes the Dirac points at zero energy. However, the chiral symmetry is broken by the chemical potential disorder and is not responsible for CMP (See Supplementary Fig. 10 and Section IV.E for details).
