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…
What can we learn from nonequilibrium response of a strange metal?
B. A. Polyak, V. S. Khrapai, E. S. Tikhonov
We critically address the recent experiment [Science 382, 907 (2023)] on nonequilibrium transport and noise in a strange metal YbRh2Si2 patterned into the nanowire shape. In the lo…
Comment on "Shot noise in a strange metal"
B. A. Polyak, E. S. Tikhonov, V. S. Khrapai
The recent paper [Science 382, 907 (2023)] reports on the measurements of shot noise in the heavy fermion strange metal YbRh2Si2 patterned into the nanowire shape. The authors clai…
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…
