Almost constant voltage plateaus on the V(I) curves of long quasi-one-dimensional superconducting aluminum wires placed in magnetic field at temperatures T slightly below the critical superconducting temperature Tc were found which were unexpected for the sample geometry and parameters of the experiment. The plateaus are assumed to be subharmonics of a superconducting gap and arise due to the multiple Andreev reflection and strong quasiparticle overheating in the wire nonequilibrium region. The plateaus are evidence of coexistence of superconductivity and dissipation in such wires. The results presented in the paper could not be described by existing theories.

  1. Critical temperatures and critical currents of wide and narrow quasi-one-dimensional superconducting aluminum structures in zero magnetic field

    cond-mat.supr-con 2026-04 unverdicted novelty 5.0

    Narrower quasi-1D aluminum structures exhibit lower critical temperatures and current densities than wider ones, with switching currents matching Kupriyanov-Lukichev theory at low T and Josephson SNS behavior near Tc.

  2. Unusual critical currents in quasi-one-dimensional superconducting aluminum two-width structures in a magnetic field

    cond-mat.supr-con 2026-04 unverdicted novelty 4.0

    Experimental switching currents in aluminum two-width quasi-1D structures are nonlocal and persist in high magnetic fields, radically differing from Ginzburg-Landau theory predictions and challenging known descriptions.

  3. Negative nonlocal and local voltages (resistances) in a quasi-one-dimensional superconducting aluminum structure

    cond-mat.supr-con 2026-04 unverdicted novelty 3.0

    Negative voltages observed in quasi-1D Al superconductor structure due to quasiparticle current at N-S interface, with temperature and field dependences modeled using equilibrium or nonequilibrium fluctuations.
