a The unit cell and hoppings of H8B. b The evolution of Dirac points between the fourth and fifth bands. Red (blue) circles indicate Dirac points with positive (negative) chirality (defined in Section IV.D of Supplementary Information), and the green crosses correspond to Dirac points between the third and fourth bands. The blue and red arrows indicate the evolution directions of Dirac points when \(\tilde{t}\) increases. c–e Band structures with \(a\tilde{t}/v=0,\pi /2,\pi\) (correspond to θ = − π/2, 0, π/2, respectively). The blue capital letters indicate the irreps at high symmetry points. The dashed lines indicate zero energy. f The normalized localization length as functions of \(\tilde{t}\) at various transversal sizes L and fixed disorder strength W = 2v/a and Fermi level EF = 0. The used longitudinal size is M = 107 and the precision (σΛ/Λ) has reached 3%. (For lattice models, `size' refers to the number of unit cells.) g The phase diagram in \(\tilde{t}-W\) plane for EF = 0, where the green region represents the CMP enclosed by the LP.
