Estimation of intraband and interband relative coupling constants from temperature dependences of the order parameter for two-gap superconductors

S. A. Kuzmichev, T. E. Kuzmicheva, S. N. Tchesnokov +2

We present temperature dependences of the large and the small superconducting gaps measured directly by SnS-Andreev spectroscopy in various Fe-based superconductors and MgB $_{2}$ . Th…

Intrinsic Multiple Andreev Reflections in layered Th-doped Sm $_{1 - x}$ Th $_{x}$ OFeAs

T. E. Kuzmicheva, S. A. Kuzmichev, S. N. Tchesnokov +1

Layered oxypnictide Sm $_{1 - x}$ Th $_{x}$ OFeAs (Sm-1111) is an ideal candidate to be probed by intrinsic multiple Andreev reflections effect (IMARE) spectroscopy. Using the classical "b…

Uniform impurity scattering in two-band $s_{\pm}$ and $s_{++}$ superconductors

M. M. Korshunov, Yu. N. Togushova, O. V. Dolgov

The $s_{\pm}$ and $s_{++}$ models for the superconducting state are subject of intense studies regarding Fe-based superconductors. Depending on the parameters, disorder may leave int…

Tracing the $s_{\pm}$ -symmetry in iron pnictides by controlled disorder

Micha Benjamin Schilling, Andreas Baumgartner, Boris Gorshunov +8

Consecutive proton irradiation of iron pnictides reduces the superconducting transition temperature to decrease monotonically. Our systematic optical THz investigations of Ba(Fe$_{…

Effective action theory of Andreev level spectroscopy

Artem V. Galaktionov, Andrei D. Zaikin

With the aid of the Keldysh effective action technique we develop a microscopic theory describing Andreev level spectroscopy experiments in non-tunnel superconducting contacts. We…

Diffusive superconductors beyond Usadel approximation: Electron-hole asymmetry and large photoelectric effect

Mikhail S. Kalenkov, Andrei D. Zaikin

We extend the quasiclassical formalism for diffusive superconductors by deriving anisotropic (gradient) corrections to the Usadel equation. We demonstrate that in a number of physi…

Superconducting properties of sulfur-doped iron selenide

Mahmoud Abdel-Hafiez, Yuan-Yuan Zhang, Zi-Yu Cao +8

The recent discovery of high-temperature superconductivity in single-layer iron selenide has generated significant experimental interest for optimizing the superconducting properti…
