title: Effects of symmetry crossover in quantum transport in graphene and nanotubes.
abstract: A brief review is given here on transport properties of carbon nanotubes mainly from a theoretical point of view. The topics include an effective-mass description of electronic states and the absence of backscattering and the presence of a perfectly conducting channel except for scatterers with a potential range smaller than the lattice constant. The dynamical conductivity in the presence of a perfect channel and effects of symmetry crossover are also discussed.
