Residual gauge theory for quanta of surface plasmons
Ken-ichi Sasaki
We develop a gauge-theoretical framework to investigate the quanta of surface plasmons. Our formulation, based on quantum electrodynamics, highlights the importance of residual gau…

Chirality dependent frequency shift of radial breathing mode in metallic carbon nanotubes
K. Sasaki, R. Saito, G. Dresselhaus +3
A phonon frequency shift of the radial breathing mode for metallic single wall carbon nanotubes is predicted as a function of Fermi energy. Armchair nanotubes do not show any frequ…
