Topological classification of the single-wall carbon nanotube
Rin Okuyama, Wataru Izumida, Mikio Eto
The single-wall carbon nanotube (SWNT) can be a one-dimensional topological insulator, which is characterized by a -topological invariant, winding number. Using the ana…

Angular momentum and topology in semiconducting single-wall carbon nanotubes
W. Izumida, R. Okuyama, A. Yamakage +1
Semiconducting single-wall carbon nanotubes are classified into two types by means of orbital angular momentum of valley state, which is useful to study their low energy electronic…

Valley coupling in finite-length metallic single-wall carbon nanotubes
W. Izumida, R. Okuyama, R. Saito
Degeneracy of discrete energy levels of finite-length, metallic single-wall carbon nanotubes depends on type of nanotubes, boundary condition, length of nanotubes and spin-orbit in…
