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…
Emergent spin quantum Hall edge states at the boundary of two-dimensional electron gas proximitized by an -wave superconductor
M. V. Parfenov, V. S. Khrapai, I. S. Burmistrov
Hybrid two-dimensional electron gas-superconductor (2DEG-S) structures in a quantized magnetic field offer a promising platform for realizing new topological phases. While recent e…
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…
Local thermometry of NbSe flake with delta- noise measurements
M. G. Prokudina, A. F. Shevchun, V. S. Khrapai +1
We perform transport and noise measurements for device consisting of a thin NbSe flake laid onto the predefined gold electrodes and covered with a thin hBN flake. In the shot n…
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…
