Forward Electron-Phonon Scattering and HTS
Tunneling and point contact spectroscopy show clear phonon features and
together with optic measurements give strong support that the electron-phonon
interaction (EPI) is large in HTS oxides. Strong correlations in HTS oxides
renormalize the EPI (and interaction with impurities) so that the forward
scattering peak (FSP) develops for small hole doping \delta<<1. The FSP
mechanism explains important properties of the normal and superconducting
state.Comment: 6 pages, 5 figure
