We calculate the effect of local magnetic moments on the electron-phonon coupling in BaFe$_{2}$As$_{2}+\delta$ using the density functional perturbation theory. We show that the magnetism enhances the total electron-phonon coupling by $\sim 50%$, up

We show that the double kink-structure in the electronic self-energy of Bi2212 near the nodal point at low energy $\omega_{1}\approx 50-70$ $meV$ and at high energy at $\omega_{2}\approx 350$ $meV$, observed recently in the ARPES measurements by Vall

Thermodynamic properties of the multiband superconductor MgB$_{2}$ have often been described using a simple sum of the standard BCS expressions corresponding to $\sigma$- and $\pi$-bands. Although, it is \textit{a priori} not clear if this approach i

We argue, based on band structure calculations and Eliashberg theory, that the observed decrease of $T_c$ of Al and C doped MgB$_2$ samples can be understood mainly in terms of a band filling effect due to the electron doping by Al and C. A simple sc

Tunneling and point contact spectroscopy show clear phonon features and together with optic measurements give strong support that the electron-phonon interaction (EPI) is large in HTS oxides. Strong correlations in HTS oxides renormalize the EPI (and

We present the results of investigations of the temperature dependences of complex conductivity σ(T) = σ′(T)−iσ″(T) at frequency 9.4 GHz in series of single crystals V3+xSi1−x with different Si content. The data exhibit peculiarities typic
