Zero modes of chiral symmetric systems are stable as for symmetry preserving disorder. On a honeycomb lattice with Kekule ordering, we have demonstrated this stabilities numerically. It has been pubished in Ann. of Physics, “Robust zero modes in disordered two-dimensional honeycomb lattice with Kekulé bond ordering” by T.Kawarabayashi, Y. Inoue, R. Itagaki, Y. Hatsugai and H.Aoki. See also arXiv:2102.00575.
