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…
Efficient Cooper Pair Splitting Without Interactions
E. S. Tikhonov, V. S. Khrapai
For the three-terminal NSN device with single-mode normal terminals and without Coulomb blockade, we propose the interpretation of charge transfer process which allows us to consis…
Fate of the superconducting state in floating islands of hybrid nanowire devices
E. V. Shpagina, E. S. Tikhonov, D. Ruhstorfer +2
We investigate the impact of transport current on the superconducting order parameter in superconducting islands in full-shell epitaxial Al-InAs nanowires. Depending on a device la…
Localization of the Helical Edge States in the Absense of External Magnetic Field
A. V. Bubis, N. N. Mikhailov, S. A. Dvoretsky +2
Theoretically, the helical edge states of two-dimensional topological insulators are protected from coherent backscattering due to nonmagnetic disorder provided electron interactio…
