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…

Controlling edge states of zigzag carbon nanotubes by the Aharonov-Bohm flux
K. Sasaki, S. Murakami, R. Saito +1
It has been known theoretically that localized states exist around zigzag edges of a graphite ribbon and of a carbon nanotube, whose energy eigenvalues are located between conducti…

Fractional Flux Periodicity in Doped Carbon Nanotubes
K. Sasaki, S. Murakami, R. Saito
An anomalous magnetic flux periodicity of the ground state is predicted in two-dimensional cylindrical surface composed of square and honeycomb lattice. The ground state and persis…
