Impact of Electron-Phonon Coupling on Near-Field Optical Spectra

J. P. Carbotte, J. P. F. LeBlanc, Phillip E. C. Ashby

The finite momentum transfer ($\mathbf{q}$) longitudinal optical response ${\sigma }^L(\mathbf{q},\omega )$ of graphene has a peak at an energy $\omega =\hslash v_{F}q$. This corresponds directly…
