Erratum: Theory of spin Bott index for quantum spin Hall states in nonperiodic systems (Physical Review B (2018) 98 (125130) DOI: 10.1103/PhysRevB.98.125130)

Abstract

There was a convergence error in the original Fig. 3 because too large a cutoff threshold was used in the calculations. Below is the corrected Fig. 3, which shows excellent agreement between the spin Bott index Bs and the Z2 invariant around the phase-transition point even in a system with spin-mixing perturbations. This numerical correction does not affect any other results and conclusions of the original paper. (Figure Presented).
