Thermal bottleneck in a freely suspended superconducting island on InAs nanowire
E. V. Shpagina, E. S. Tikhonov, D. Ruhstorfer +2
We investigate the heat balance in superconducting islands (S-islands) formed in epitaxial Al/InAs nanowires (NWs) freely suspended above the substrate. We employ a Joule spectrosc…

Superconducting bistability in floating Al islands of hybrid Al/InAs nanowires
E. V. Shpagina, E. S. Tikhonov, D. Ruhstorfer +2
We investigate a non-equilibrium aspect of the current-driven superconducting-normal phase transition in floating Al islands of epitaxial full-shell Al/InAs nanowires. Within a tra…

Conductance measurements cannot distinguish crossed Andreev reflection from elastic co-tunneling in normal--superconductor--normal junctions
E. S. Tikhonov, V. S. Khrapai
We argue that the interpretation of the experiment [Nature Physics 21, 708-715 (2025)] is misleading in two respects. First, the bias voltages impact the non-local differential con…
