Self-energy Effect of Superconducting Energy Gap in Point-Contact Spectra of MgB
I. K. Yanson, S. I. Beloborod'ko, Yu. G. Naidyuk +2
In strong-coupling superconductors with a short electron mean free path the self-energy effects in the superconducting order parameter play a major role in the phonon manifestation…

Why is the ARPES anti-nodal singularity at 40 meV shifted in superconducting state of HTSC, but the kink at 70 meV is not?
M. L. Kulic, O. V. Dolgov
The theoretical model for the quasiparticle self-energy in HTSC is proposed, which is based on the forward scattering peak in the electron-phonon (EPI) interaction. By assuming tha…
