Abstract
Robustness of zero-modes of two-dimensional Dirac fermions is examined numerically for the honeycomb lattice in the presence of Kekul\'e bond ordering. The split Landau levels in a magnetic field as well as the zero-modes generated by topological defects in the Kekul\'e ordering are shown to exhibit anomalous robustness against disorder when the chiral symmetry is respected.
