Неравновесное состояние в квазиодномерных сверхпроводящих каналах
JETP Letters. 2026. Vol. 124. No. 6. P. 1–16.
Superconducting properties of metallic micro- and nanowires can be entirely different from those of bulk superconductors. Of particular interest is the nonequilibrium current-induced state of a quasi-one-dimensional superconducting channel. The most interesting phenomenon here is the stepped I–V characteristic, explained by a process known as phase slip center activation. If the origin of such step-like I-V dependencies is at least qualitatively well understood, a commonly accepted explanation for the step-like R(T) characteristics is still missing. We review theoretical and experimental activities in the field and demonstrate dramatic progress in understanding of the phenomenon of quasi-one-dimensional superconductivity.

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

This paper compares the ranging precision of direct time-of-flight (dToF) and non-line-of-sight (NLOS) LiDAR architectures, both using a superconducting nanowire single-photon detector (SNSPD). Both systems operate at 1550 nm with a 50 ps pulsed laser and time-correlated single-photon counting (TCSPC). The dToF configuration achieved approximately 100 µm precision at 10 m, while the NLOS configuration achieved 500 µm precision for ...

We theoretically study the nonequilibrium dynamics of the order parameter of a superconducting ring inhomogeneously quenched through its transition temperature. Numerical simulations based on spectral decomposition of the time-dependent Ginzburg-Landau equation reveal that current-carrying superconducting states can be generated in the ring under certain fast local temperature quench conditions. We also show that illumination of ...

Rapid miniaturization of electronic devices and circuits demands profound understanding of
fluctuation phenomena at the nanoscale. Superconducting nanowires – serving as important
building blocks for such devices – may seriously suffer from fluctuations which tend to
destroy long-range order and suppress superconductivity. In particular, quantum phase slips
(QPS) proliferating at low temperatures may turn a quasi-one-dimensional superconductor
into a resistor ...
