Stabilization mechanism of edge states in graphene
K. Sasaki, S. Murakami, R. Saito
It has been known that edge states of a graphite ribbon are zero-energy, localized eigen-states. We show that next nearest-neighbor hopping process decreases the energy of the edge…

Re-parameterization Invariance in Fractional Flux Periodicity
Shuichi Murakami, Ken-ichi Sasaki, Riichiro Saito
We analyze a common feature of a nontrivial fractional flux periodicity in two-dimensional systems. We demonstrate that an addition of fractional flux can be absorbed into re-param…
