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 in the limit of infinite onsite repulsion at the impurity site. We discuss the local non-Fermi liquid behaviour at temperatures below the Kondo temperature TK. The density of states of localized electrons has a singularity at about |ω|1/2, which gives rise to a pseudogap at the Kondo…

Reentrant Kondo effect in Landau-quantized graphene: Influence of the chemical potential

We have studied the effect of an Anderson impurity in Landau quantized graphene, with special emphasis on the influence of the chemical potential. Within the slave-boson mean-field theory, we found

LETTER TO THE EDITOR: Novel electronic wave interference patterns in nanographene sheets

Superperiodic patterns extending over a large distance in a nanographene sheet observed using a scanning tunnelling microscope are discussed in terms of the interference of electronic wavefunctions.

Impurity Scattering in Carbon Nanotubes Absence of Back Scattering

The effective potential of an impurity in a k · p scheme is derived in two-dimensional graphite sheet. When the potential range is smaller than the lattice constant, it has an off-diagonal matrix

ELECTRONIC STATES OF METALLIC AND SEMICONDUCTING CARBON NANOTUBES WITH BOND AND SITE DISORDER

Disorder effects on the density of states in carbon nanotubes are analyzed by a tight-binding model with Gaussian bond or site disorder. Metallic armchair and semiconducting zigzag nanotubes are

Luttinger-liquid behaviour in carbon nanotubes

Electron transport in conductors is usually well described by Fermi-liquid theory, which assumes that the energy states of the electrons near the Fermi level EF are not qualitatively altered by

Electronic States of Carbon Nanotubes

The π-electron states of carbon nanotubes (CN's) in magnetic fields are calculated in the effective-mass theory. A sensitive change of CN from metal to semiconductor depending on its structure is

Disordered magnetism at the metal-insulator threshold in nano-graphite-based carbon materials

These behaviors are explained in terms of disordered magnetism caused by random strengths of inter-nano-graphite antiferromagnetic interactions mediated by pi-conduction carriers.

Self-consistent perturbation theory of the anderson model: Ground state properties

The zero temperature limit of the self-consistent perturbation theory of a degenerate Anderson impurityin a metal is partially solved with analytical methods. In particular, the energy scales

Kondo effect in a Tomonaga-Luttinger liquid.

The Kondo eA'ect in a repulsively interacting electron system (Tomonaga-Luttinger liquid) is studied and it is shown that the Kondo coupling is connected to the strong-coupling regime not only for the antiferromagnetic but also for the ferromagnetic case.

Resistivity in the extended slave-boson mean field theory of the Anderson alloy system

Resistivity in the Anderson alloy system is calculated using the extended slave-boson mean field theory developed by Xu and Li (1988). The author finds that the value of the peak of resistivity as a
