To evaluate the disorder-driven metal-insulator transition in topological insulators and calculate the critical exponent governing localization length scaling.
Performed a finite-size scaling analysis of localization length in disordered topological insulator lattice systems.
Assessed scaling universality and critical exponent behavior within the orthogonal symmetry class framework.
Identified a disorder-driven metal-insulator transition characterized by a critical exponent of ν ≈ 2.7.
Found no deviation from standard metal-ordinary insulator transition scaling within the orthogonal symmetry class.
Observed proximity of ν ≈ 2.7 to φ² (≈ 2.618), pointing to a potential resonance with golden ratio scaling.
