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…
Kohn Anomaly in Raman Spectroscopy of Single Wall Carbon Nanotubes
K. Sasaki, H. Farhat, R. Saito +1
Phonon softening phenomena of the point optical modes including the longitudinal optical mode, transverse optical mode and radial breathing mode in "metallic" single wall carbo…
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…
The Gluon Self-Energy in the Coulomb and Temporal Axial Gauges via the Pinch Technique
M. Passera, K. Sasaki
The -matrix pinch technique is used to derive an effective gluon self-energy to one-loop order, when the theory is quantized in the Coulomb gauge (CG) and in the temporal axial…
