Mass synthesis of fullerenes and helical microtubules of graphite has opened new avenues for the exploration of their novel electronic, magnetic, dielectric, and thermodynamic properties not just experimentally but also theoretically. In particular, physics at mesoscopic length scales often leads to unexpected phenomena due to the predominantly quantum nature of the system. If the mesoscopic structure has curved geometry, it adds further richness to the system.Subjects--Topical Terms:

520 $a Mass synthesis of fullerenes and helical microtubules of graphite has opened new avenues for the exploration of their novel electronic, magnetic, dielectric, and thermodynamic properties not just experimentally but also theoretically. In particular, physics at mesoscopic length scales often leads to unexpected phenomena due to the predominantly quantum nature of the system. If the mesoscopic structure has curved geometry, it adds further richness to the system.
520 $a We propose a simple model for the electronic structure of these low dimensional materials. We treat the $\pi$ electrons as an interacting two dimensional electron gas restricted to the surface of the curved carbon clusters. The quasi-particle energy spectra are obtained for both the spherical fullerenes and the carbon nanotubes within the Hartree Fock mean field approximation.
520 $a Using the quasiparticle energy spectrum as input, the collective excitation spectra and density-density response function are calculated within the random phase approximation (RPA). The plasmon energy spectra are obtained by searching for the zeros of the RPA dielectric function for both the spherical fullerenes and the carbon nanotubes. The multipole plasmon spectra are calculated for the spherical fullerenes, and the intrasubband as well as the intersubband plasmon dispersion are calculated for the carbon nanotubes. Furthermore, a variational method is introduced to study the effect of electronic correlations on the finite curved fullerenes and the infinite carbon nanotubes.
520 $a Finally, we apply the model to calculate the material properties, and derive the atom-plasmon interaction for an excited atom in a carbon nanotube. The atom-plasmon interaction is then used to calculate the lifetime of the excited atom in the cavity using standard cavity quantum electrodynamics techniques (QED). The lifetimes for dipole allowed and forbidden transitions are calculated. Their implications for electromagnetic applications are investigated and subsequent refinements of the theory discussed.
