Bulk-edge correspondence with generalized chiral symmetry
Dirac cones are generically tilted when realized in a realistic material. This gapless structure is effectivel […]

Kekule ordering and zero modes with disorder
Zero modes of chiral symmetric systems are stable as for symmetry preserving disorder. On a honeycomb lattice […]
