Comment on: Role of inelastic tunneling through the insulating barrier in scanning-tunneling-microscope experiments on cuprate superconductors

A. R. Bishop, S. D. Conradson, A. Bussmann-Holder +7

In a recent letter [1] Pilgram, Rice and Sigrist (PRS) propose to perform oxygen isotope dependent conductivity measurements along the c-axis of the cuprate superconductor BSSCO. I…

Reply to Samuely et al. cond-mat/0503153

J. Kortus, O. V. Dolgov, R. K. Kremer +1

Samuely et al. (cond-mat/0503153) make the strong claim that our letter is 'contradicting several established experimental results'. As we will show below this is not justified and…

Band filling and interband scattering effects in MgB: C vs Al doping

Jens Kortus, Oleg V. Dolgov, Reinhard K. Kremer +1

We argue, based on band structure calculations and Eliashberg theory, that the observed decrease of of Al and C doped MgB samples can be understood mainly in terms of a b…

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…

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…
