In the middle of the last century, it was demonstrated that with a decrease in the size of superconducting
structures, for example, the thickness of a thin film, its critical temperature Tc shifts by a certain amount.
It increases in aluminum, tin, and indium, and decreases in mercury, niobium and lead. However, there is
still no generally accepted ...

High-quality aluminum films on GaAs substrates are studied experimentally. The critical temperature of superconductivity is found to increase markedly with decreasing the film thickness. The observed phenomenon is considered as a manifestation of the quantum confinement effect, which affects both the density of states and the electron–phonon interaction. ...

The Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction of magnetic impurities in a superconductor exponentially decreases when the distance between them is larger than the superconductor's coherence length, because this interaction is mediated by quasiparticles, which have a gap in their energy spectrum. At the same time, the spin-singlet superconducting condensate was always assumed to stay neutral to magnetic ...

The magnetization in a superconductor induced due to the inverse proximity effect is
investigated in hybrid bilayers containing a superconductor and a ferromagnetic
insulator or a strongly spin-polarized ferromagnetic metal. The study is performed
within a quasiclassical Green function framework, wherein Usadel equations are solved
with boundary conditions appropriate for strongly spin-polarized ferromagnetic
materials. A comparison with recent experimental data ...

The spin-galvanic (inverse Edelstein) and inverse spin-Hall effects are calculated for a hybrid
system that combines thin superconductor and Rashba-metal layers. These effects are produced by
a nonequilibrium spin polarization which is injected into the normal metal layer. This polarization
gives rise to an electric potential that relaxes within some characteristic length, which is determined
by the Andreev reflection. ...

Экспериментально исследовались высококачественные пленки алюминия на подложках из GaAs. Был обнаружен заметный рост критической температуры сверхпроводящего перехода с уменьшением толщины пленки. Эффект интерпретируется как проявление квантового размерного эффекта, влияющего как на плотность состояний электронов, так и на электрон-фононное взаимодействие. ...

A weak parallel Zeeman field combined with the spin-orbit coupling can induce the supercurrent in
an s-wave two-dimensional superconductor. At the same time, the thermodynamically equilibrium
state of such a system is characterized by the helix phase where the order parameter varies in space
as exp(iQr). In this state the electric current that is induced by the Zeeman ...

We study theoretically the Josephson effect between two two-band superconductors respecting time-reversal
symmetry, where we assume a spin-singlet s-wave pair potential in each conduction band. The superconducting
phase at the first band ϕ1 and that at the second band ϕ2 characterize a two-band superconducting state. We
consider a Josephson junction where an insulating barrier separates two such two-band ...

We consider the spin-orbit-induced spin Hall effect and spin swapping in diffusive superconductors.
By employing the non-equilibrium Keldysh Green’s function technique in the quasiclassical
approximation, we derive coupled transport equations for the spectral spin and particle distributions
and for the energy density in the elastic scattering regime. We compute four contributions to
the spin Hall conductivity, namely, skew scattering, ...

Relatively little is known about differences in the quality of engineering education within and across countries because of the lack of valid instruments that allow for the assessment and comparison of engineering students’ skill gains. The purpose of our study is to develop and validate instruments that can be used to compare student skill gains ...

The framework of simple opposition realism - anti-realism is not enough to analyze the views on the reality of unobservable objects of quantum theory. First, it is necessary to distinguish between realism in relation to the theory and realism in relation to the theory’s objects. Secondly, realism in relation to classical objects can be combined, ...

Exploring life cycles of fungi is insightful for understanding their basic biology and can highlight their ecology. Here, we dissected the sexual and asexual life cycles of the obligate alkalophilic ascomycete Sodiomyces alkalinus that thrives at extremely high pH of soda lakes. Sodiomyces alkalinus develops acremonium-type asexual sporulation, commonly found in ascomycetous fungi. However, the ...

In this short review, we first discuss the results, which are mainly devoted to the generalizations of the famous Kohn–Luttinger mechanism of superconductivity in purely repulsive fermion systems at low electron densities. In the context of repulsive-U Hubbard model and Shubin–Vonsovsky model we consider briefly the superconducting phase diagrams and the symmetries of the order parameter ...
