Curvature induced optical phonon frequency shift in metallic carbon nanotubes
K. Sasaki, R. Saito, G. Dresselhaus +3
The quantum corrections to the frequencies of the point longitudinal optical (LO) and transverse optical (TO) phonon modes in carbon nanotubes are investigated theoretically. T…
Local density of states at zigzag edge of carbon nanotubes and graphene
K. Sasaki, K. Sato, J. Jiang +3
The electron-phonon matrix element for edge states of carbon nanotubes and graphene at zigzag edges is calculated for obtaining renormalized energy dispersion of the edge states. S…
Kinematics of Persistent Currents in Nanotubes and Tori -Time-reversal symmetric gauge field and its application-
K. Sasaki, Y. Kawazoe
The basic properties of conducting electrons in carbon nanotubes are reviewed from a theoretical perspective, and studies performed on persistent currents in toroidal carbon nanotu…
Fractional Flux Periodicity in Doped Carbon Nanotubes
K. Sasaki, S. Murakami, R. Saito
An anomalous magnetic flux periodicity of the ground state is predicted in two-dimensional cylindrical surface composed of square and honeycomb lattice. The ground state and persis…
Characteristic Behavior of Toroidal Carbon Nanotubes: Kinematics of Persistent Currents
K. Sasaki, Y. Kawazoe
The electrical properties of a carbon nanotube depend strongly on its lattice structure as defined by chiral and translational vectors. A toroidal shape for a nanotube allows vario…
Instability of capacitance mode in multi-walled nanotubes
K. Sasaki
Conditions for intra and inter layer Coulomb interactions in multi-walled carbon nanotubes are derived from stability of capacitance excitations. It is pointed out, supposing the s…
