Forward Electron–Phonon Scattering in Normal and Superconducting States
Forward Electron–Phonon Scattering in Normal and Superconducting States
The sharp forward electron–phonon (FEP) and impurity (FIS) scattering change the normal and superconducting properties significantly. The pseudo-gap like features are present in the density of states for ω<Ω, where Ω is the phonon frequency. The superconducting critical temperature T c , due to the FEP pairing, is linear with …
