Doping evolution of the gap structure and spin-fluctuation pairing in superconductors
A. E. Karakozov, M. V. Magnitskaya, L. S. Kadyrov +1
Doping dependence of the superconducting state structure and spin-fluctuation pairing mechanism in the family is studied. BCS-like analysis of experi…
Temperature dependence of resistivity at the transition to a charge density wave state in rare-earth tritellurides
Kaushal Kumar Kesharpu, Pavel Dmitrievich Grigoriev
About a half of the Fermi surface in rare-earth tritellurides RT e3 becomes gapped below the transition to a charge-density-wave (CDW) state, as revealed by ARPES data. However, th…
Intrinsic dissipation in superconducting junctions probed by qubit spectroscopy
Dmitry S. Golubev, Artem V. Galaktionov, Andrei D. Zaikin
We propose to study frequency dependent intrinsic dissipation in a highly transparent Josephson junction by means of qubit spectroscopy. The spectral density of the effective dissi…
Relaxation of Nonequilibrium Quasiparticles in Mesoscopic Size Superconductors
K. Yu. Arutyunov, S. A Chernyaev, T. Karabassov +3
Rapid development of micro- and nanofabrication methods have provoked interest and enabled experimental studies of electronic properties of a vast class of (sub)micrometer-size sol…
Temperature-dependent transitions in the multiband model for Fe-based superconductors with impurities
V. A. Shestakov, M. M. Korshunov, O. V. Dolgov
We study the dependence of the superconducting gaps on both the disorder and the temperature within the two-band model for iron-based materials. In the clean limit, the system is i…
Unique interplay between superconducting and ferromagnetic orders in EuRbFeAs
V. S. Stolyarov, A. Casano, M. A. Belyanchikov +15
Transport, magnetic and optical investigations on EuRbFeAs single crystals evidence that the ferromagnetic ordering of the Eu magnetic moments at K, below t…
Self-consistent and Maxwell approximations to describe the excess conductivity anisotropy in FeSe above superconducting transition temperature
Kaushal K. Kesharpu, Pavel D. Grigoriev, Darya I. Lazeva +1
Using the self-consistent approximation we calculate conductivity in an anisotropic heterogeneous media with superconducting inclusions and compare the results with those obtained…
Superconducting gap symmetry in BaFeNiAs superconductor
T. E. Kuzmicheva, S. A. Kuzmichev, A. V. Sadakov +8
We report on the Andreev spectroscopy and specific heat of high-quality single crystals BaFeNiAs. The intrinsic multiple Andreev reflection spectroscopy revea…
High-pressure effects on isotropic superconductivity in the iron-free layered pnictide superconductor BaPd2As2
M. Abdel-Hafiez, Y. Zhao, Z. Huang +14
While the layered 122 iron arsenide superconductors are highly anisotropic, unconventional, and exhibit several forms of electronic orders that coexist or compete with superconduct…
Reduction of the electrodynamics of superconductors to those for conductors with the incorporation of spatial dispersion
M. A. Dresvyannikov, A. P. Chernyaev, A. L. Karuzskii +4
We derive general frequency dependencies of the surface impedance modulus for conductors without the dc dissipation, i. e. for superconductors or perfect conductors. The frequency-…
Evidence of a multiple boson emission in SmThOFeAs
S. A. Kuzmichev, T. E. Kuzmicheva, N. D. Zhigadlo
We studied a reproducible fine structure observed in dynamic conductance spectra of Andreev arrays in SmThOFeAs superconductors with various thorium concentrations ($x…
Structural distortion behind the nematic superconductivity in SrBiSe
A. Yu. Kuntsevich, M. A. Bryzgalov, V. A. Prudkoglyad +3
An archetypical layered topological insulator BiSe becomes superconductive upon doping with Sr, Nb or Cu. Superconducting properties of these materials in the presence of i…
Towards the issue of the origin of Fermi surface, pseudogaps and Fermi arcs in cuprate HTSCs
K. V. Mitsen, O. M. Ivanenko
Earlier we have proposed a new approach to the analysis of superconducting phase diagrams for cuprates and pnictides and have shown that the positions of superconducting domes on t…
