Quantum Interferences in the Raman Cross Section for the Radial Breathing Mode in Metalic Carbon Nanotubes
G. Bussi, J. Menendez, J. Ren +2
The lineshapes of the Raman excitation profiles for radial breathing modes in carbon nanotubes are shown to be strongly affected by interference effects that arise whenever strong…

Excitons in carbon nanotubes: an ab initio symmetry-based approach
Eric Chang, Giovanni Bussi, Alice Ruini +1
The optical absorption spectrum of the carbon (4,2) nanotube is computed using an ab-initio many-body approach which takes into account excitonic effects. We develop a new method i…
