  The honeycomb carbon structure of graphene and nanotubes has a dynamics which
can give rise to a spectrum. This can be excited via the interaction with an
external electromagnetic field. In this work, non-linear waves on graphene and
nanotubes associated with the carbon structure are investigated using a gauge
model. Typical energies are estimated and there scaling with the nanoribbon
width investigated. Furthermore, the soliton-photon interaction depends on the
incident photon polarization. In particular, we find that the nanoribbon is
transparent when the polarization is along the largest length. Relying on the
scaling with the width, we suggest a way to experimentally identify the soliton
waves in nanoribbons.
