Buckling of Carbon Nanotubes: A State of the Art Review
Hiroyuki Shima
The nonlinear mechanical response of carbon nanotubes, referred to as their "buckling" behavior, is a major topic in the nanotube research community. Buckling means a deformation p…
Electronic spectral shift of oxygen-filled (6,6) carbon nanotubes
Hiroyuki Shima, Hideo Yoshioka
Electronic state modulation of the armchair (6,6) carbon nanotubes filled with a linear assembly of oxygen molecules is addressed theoretically. Ferromagnetic coupling of encapsula…
Flexible control of the Peierls transition in metallic C polymers
Shota Ono, Hiroyuki Shima
The metal-semiconductor transition of peanut-shaped fullerene (C) polymers is clarified by considering the electron-phonon coupling in the uneven structure of the polymers.…
Phonon dispersion and electron-phonon interaction in peanut-shaped fullerene polymers
Shota Ono, Hiroyuki Shima
We reveal that the periodic radius modulation peculiar to one-dimensional (1D) peanut-shaped fullerene (C) polymers exerts a strong influence on their low-frequency phonon s…
Density of states anomalies in multichannel quantum wires
Hideo Yoshioka, Hiroyuki Shima
We reformulate the Tomonaga--Luttinger liquid theory for quasi-one-dimensional Fermion systems with many subbands across the Fermi energy. Our theory enables us to obtain a rigorou…
