High-temperature superconductivity in hydrides
I. A. Troyan, D. V. Semenok, A. G. Ivanova +7
Over the past six years (2015-2021), many superconducting hydrides with critical temperatures up to 250 K, which are currently record highs, have been discovered. Now we ca…
Direct observation of the spin exciton in Andreev spectroscopy of iron-based superconductors
M. M. Korshunov, S. A. Kuzmichev, T. E. Kuzmicheva
Quasiparticle excitations provide viable information on the physics of unconventional superconductors. Higgs and Leggett modes are some of the classic examples. Another important b…
Nonlinear microwave response of clean superconducting films
A. A. Radkevich, A. G. Semenov
We develop an explicitly gauge-invariant semiclassical approach to investigate nonlinear response of superconductors to monochromatic THz radiation. We demonstrate that in clean su…
Local transformation of the Electronic Structure and Generation of Free Carriers in Cuprates and Ferropnictides under Heterovalent and Isovalent Doping
Kirill Mitsen, Olga Ivanenko
We have previously shown that most of the anomalies in the superconducting characteristics of cuprates and ferropnictides observed at dopant concentrations within the superconducti…
Anomalous metallic oxygen band in the potential superconductor KCaFeAsO
Nikita S. Pavlov, Kirill S. Pervakov, Igor A. Nekrasov
The electronic structure, magnetism and Fermi surface of a hole self-doped potential iron-based superconductor KCaFeAsO (12442) were studied by a first-principes DF…
Hybrid helical state and superconducting diode effect in S/F/TI heterostructures
T. Karabassov, I. V. Bobkova, A. A. Golubov +1
It is well-known that the ground state of homogeneous superconducting systems with spin-orbit coupling (SOC) in the presence of the Zeeman field is the so-called helical state, whi…
Phase-coherent thermoelectricity in superconducting hybrids (Brief Review)
Mikhail S. Kalenkov, Andrei D. Zaikin
We review some recent advances in studies of phase-coherent thermoelectric effects in superconducting hybrid structures such as, e.g., Andreev interferometers. We elucidate a numbe…
Suppression of fluctuations in a two-band superconductor with a quasi-1D band
A. A. Shanenko, T. T. Saraiva, A. Vagov +2
Chain-like structured superconductive materials (such as A_2Cr_3As_3, with A = K, Rb, Cs) exhibit the multiband electronic structure of single-particle states, where coexisting qua…
