| Research Abstract |
The electron motion in graphene is governed by the Weyl equation for massless neutrino. This equation has a topological singularity at zero energy, leading to various interesting phenomena. The most intriguing property is the delta-function singularity in the diamagnetic susceptibility, the origin of which is clarified through theoretical studied from various aspects. Effects on transport properties are also the subject of the intensive study, including the magneto-phonon resonance. Environment effects on excitons in carbon nanotubes are also studied.
