Abstract

The article reviews recent progress in the theoretical understanding of near-field surface electromagnetic phenomena in pristine and atomically doped carbon nanotubes. The phenomena involving strong coupling effects are outlined. They are the optical absorption by single-walled carbon nanotubes doped with single atoms or ions in the frequency range close to the atomic transition frequency, the entanglement of the pair of atomic qubits strongly coupled to a common high-finesse surface photonic mode of the nanotube, and the optical response of the strongly coupled surface exciton-plasmon excitations in pristine semiconducting carbon nanotubes. The phenomena reviewed have a great potential to be exploited for the future development of the nanotube based tunable optoelectronic device applications in areas such as nanophotonics, nanoplasmonics, cavity quantum electrodynamics, and quantum information science.
