The "unusual" isotope shift in high-temperature superconductors can be explained by the usual theory of the electron-phonon interaction

E. G. Maksimov, O. V. Dolgov, M. L. Kulic

We show that recent ARPES results on the "unusual" oxygen isotope shift in the real part of the self-energy in the optimally doped samples can be qualitatively (and semi-q…

Can the bosonic coupling constant be extracted from the ARPES scattering rate in cuprate superconductors?

Miodrag L. Kulic

The recent ARPES results for the imaginary part of the self-energy obtained on a number of HTSC bismuthates \cite{Kordyuk} are analyzed. By accepting the ''Fermi-Bose'' {\it divisi…

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…

Thermoelectric Effects in S-N-S Weak Links with Heavy Fermions as The Normal Metal: A Possibility for Thermosensors

Miodrag L. Kulic

It is shown that S-N-S weak links with an heavy-fermion metal as the weak link (N) can be useful thermosensors. This property is due to the large thermopower of heavy-fermion metal…

Josephson Effect in Magnetic Superconductors with Spiral Magnetic Order

Miodrag L. Kulic, Igor M. Kulic

It is shown that in magnetic superconductors with spiral magnetic order the Josephson current has an additional contribution which depends: (i) on the relative orientation (magneti…

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…
