Supersymmetry and Correlated Electrons in Graphene Quantum Hall Effect
Motohiko Ezawa
We present a supersymmetric description of the quantum Hall effect (QHE) in graphene. The noninteracting system is supersymmetric separately at the so-called K and K' points of the…

Supersymmetry and Unconventional Quantum Hall Effect in Graphene
Motohiko Ezawa
We present a unified description of the quantum Hall effect in graphene on the basis of the 8-component Dirac Hamiltonian and the supersymmetric (SUSY) quantum mechanics. It is rem…

Peculiar Width Dependence of the Electronic Property of Carbon Nanoribbons
Motohiko Ezawa
Nanoribbons (nanographite ribbons) are carbon systems analogous to carbon nanotubes. We characterize a wide class of nanoribbons by a set of two integers , and then define t…
