Nonadiabatic Contribution to the Quasiparticle Self-Energy in Systems with Strong Electron-Phonon Interaction
O. V. Danylenko, O. V. Dolgov
We investigate effects of a nonadiabatic electron-phonon(boson) interaction on the quasiparticle self-energy in the lowest order in the coupling constant. Existing approaches eithe…
Forward Electron-Phonon Scattering in Normal and Superconducting States
O. V. Dolgov, O. V. Danylenko, M. L. Kulic +1
The sharp forward electron-phonon and impurity scattering change the normal and superconducting properties significantly. The pseudo-gap like features are present i…
Normal and superconducting state in the presence of forward electron-phonon and impurity scattering
O. V. Danylenko, O. V. Dolgov, M. L. Kulic +1
Impurities with the pronounced forward scattering (FS impurities) change analytical properties of the quasiparticle Green's function substantially compared to the isotropic scatter…
The Ward identity and nonadiabatic corrections to the quasiparticle self-energy
O. V. Danylenko, O. V. Dolgov, V. V. Losyakov
In some newly discovered materials the ratio of phonon to electron energies is no longer small. We have investigated the basement of the recently proposed gauge-invariant self-cons…
