Electron scattering of light in a high-Tc superconductor in the superconducting state
Kostur V. N., Eliashberg G. M.
A quasiparticle channel for the scattering of light in high-rc superconductors has been analyzed at T> Tc. The scattering of light by the carriers which interact with phonons was found to have some characteristic features, the most important of which is the presence of a broad interval in which the retardation effects play an important role.
