Abstract

The quantum Hall effect (QHE) in graphene has a peculiar edge mode at E = 0 that resides right within the n = 0 Landau level as protected by the chiral symmetry, in contrast that the usual edge states in the quantum Hall effect (QHE) reside between adjacent Landau levels. We investigate edge states of graphene with the Kekulé bond order, which respect the chiral symmetry using the entanglement entropy.
