Local non-Fermi liquid theory of magnetic impurity effects in metallic carbon nanotubes

Magnetic impurity effects on metallic carbon nanotubes are studied theoretically. The resolvent method for the multichannel Kondo effect is applied to the band structure of the k(.)p perturbation hamiltonian. The local non-Fermi liquid behavior is realized at temperatures lower than the Kondo temperature TK. The density of states of the localized electron has a singularity similar to \w\(1/2) which gives rise to a pseudo gap at the Kondo resonance in lon temperatures. The temperature dependence of the electronic resistivity is predicted as T-1/2. and the imaginary part of dynamical susceptibilities has the \w\(1/2) dependence. Possible experimental observations are discussed.
