Exciton Dynamics in Carbon Nanotubes: From the Luttinger Liquid to Harmonic Oscillators

M. C. Sweeney, J. D. Eaves

Published 2013-05-28Version 1

We show that the absorption spectrum in semiconducting nanotubes can be determined using the bosonization technique combined with mean-field theory and a harmonic approximation. Our results indicate that a multiple band semiconducting nanotube reduces to a system of weakly coupled harmonic oscillators. Additionally, the quasiparticle nature of the electron and hole that comprise an optical exciton emerges naturally from the bosonized model.
