Link between superconductivity and a Lifshitz transition in intercalated BiSe
A. Almoalem, I. Silber, S. Sandik +12
Topological superconductivity is an exotic phase of matter in which the fully gapped superconducting bulk hosts gapless Majorana surface states protected by topology. Intercalation…
Inhomogeneous superconductivity in LuxZr1-xB12 dodecaborides with dynamic charge stripes
A. Azarevich, A. Bogach, V. Glushkov +13
We have studied the normal and superconductive state characteristics (resistivity, Hall coefficient, heat capacity and magnetization) of model strongly correlated electronic system…
Long-range Josephson effect controlled by temperature gradient and circuit topology
Mikhail S. Kalenkov, Andrei D. Zaikin
We demonstrate that the supercurrent can be strongly enhanced in cross-like superconducting hybrid nanostructures (X-junctions) exposed to a temperature gradient. At temperatures T…
Superconductivity at 253 K in lanthanum-yttrium ternary hydrides
Dmitrii V. Semenok, Ivan A. Troyan, Alexander G. Kvashnin +14
Polyhydrides offer intriguing perspectives as high-temperature superconductors. Here we report the high-pressure synthesis of a series of lanthanum-yttrium ternary hydrides: cubic…
Optical and Hidden Transport Properties of BaFeNiAs Film
Yu. A. Aleshchenko, A. V. Muratov, G. A. Ummarino +3
Optical spectroscopy was used to study the electrodynamics and hidden transport properties of a BaFeNiAs thin superconducting film. We analyzed the normal s…
Reentrant superconductivity in proximity to a topological insulator
T. Karabassov, A. A. Golubov, V. M. Silkin +2
In the following paper we investigate the critical temperature behavior in the two-dimensional S/TI (S denotes superconductor and TI - topological insulator) junction with a…
Evolution of shape and volume fraction of superconducting domains with temperature and anion disorder in (TMTSF)ClO
Kaushal K. Kesharpu, Vladislav D. Kochev, Pavel D. Grigoriev
In highly anisotropic organic superconductor (TMTSF)ClO, superconducting (SC) phase coexists with metallic and spin density wave phases in the form of domains. Using the Ma…
Topology controlled phase coherence and quantum fluctuations in superconducting nanowires
Alexey Radkevich, Andrew G. Semenov, Andrei D. Zaikin
Superconducting properties of metallic nano-wires may strongly depend on specific experimental conditions. Here we consider a setup where superconducting phase fluctuations are res…
Terahertz spectroscopy evidence of possible 40 K superconductivity in rhenium-doped strontium ruthenates
Yurii Aleshchenko, Boris Gorshunov, Elena Zhukova +7
Strontium ruthenates have many similarities with copper oxide superconductors and are of particular interest for the investigation of the mechanisms and conditions which lead to hi…
Amplitudes of minima in dynamic conductance spectra of the SNS Andreev contact
Z. Popovic, S. Kuzmichev, T. Kuzmicheva
Despite several theoretical approaches describing multiple Andreev reflections (MAR) effect in superconductor-normal metal-superconductor (SNS) junction are elaborated, the problem…
Anisotropic zero-resistance onset in organic superconductors
Vladislav D. Kochev, Kaushal K. Kesharpu, Pavel D. Grigoriev
We study the coexistence of superconductivity (SC) and density-wave state and reconcile various puzzling experimental data in organic superconductors (TMTSF)PF and (TMT…
THz electrodynamics of BaFeNiAs film analyzed in the framework of multiband Eliashberg theory
G. A. Ummarino, A. V. Muratov, L. S. Kadyrov +5
The temperature dependences of the plasma frequency, superfluid density and London penetration depth were determined from terahertz spectra of conductivity and dielectric permittiv…
Anomalous current-voltage characteristics of SFIFS Josephson junctions with weak ferromagnetic interlayers
T. Karabassov, A. V. Guravova, A. Yu. Kuzin +4
We present a quantitative study of the current-voltage characteristics (CVC) of SFIFS Josephson junctions (S denotes bulk superconductor, F - metallic ferromagnet, I - insulating b…
