Diameter-Selective Raman Scattering from Vibrational Modes in Carbon Nanotubes
Single wall carbon nanotubes (SWNTs) that are found as close-packed arrays in crystalline ropes have been studied by using Raman scattering techniques with laser excitation wavelengths in the range
Structural and vibrational properties of fullerenes and nanotubes in a nonorthogonal tight‐binding scheme
A simple, computationally efficient method for the evaluation of structural and vibrational properties of carbon is presented. The scheme is based on the generalized tight‐binding molecular dynamics

Kinetic Model of Stage Transformation and Intercalation in Graphite
We derive a set of diffusion equations based on time-dependent Landau-Ginzburg theory, which is capable of describing the role of domains in stage transformations and intercalation in layered
Complex scalar fields in one dimension with fourfold phase anisotropy: Solitary-wave solutions
We present solitary-wave solutions to a set of coupled nonlinear wave equations resulting from a model Lagrangian for a complex scalar (two-component) field in one space and one time dimension in the
Bond alternation, on-site Coulomb correlations, and solitons in polyacetylene
We explore the effect of including electronic on-site Coulomb correlations on the energy of solitons in polyacetylene within an unrestricted Hartree-Fock calculation for finite chains. For parameters
Structural and vibrational properties of Si clathrates in a generalized tight-binding molecular-dynamics scheme
The structural and vibrational properties of Si in two fourfold coordinated crystalline structures (clathrates) are studied and compared with those in the diamond structure using a generalized
