Topological insulator single-electron transistors for charge sensing applications
Omargeldi Atanov, Junya Feng, Jens Brede +2
We present topological insulator (TI)-based single-electron transistors (SETs) as magnetic-field-compatible charge sensing devices that are easily integrable with TI-superconductor…
Deterministic non-local parity control and supercurrent-based detection in an Andreev molecule
Shang Zhu, Xiaozhou Yang, Mingli Liu +15
The ability to manipulate and detect the parity of quantum states in superconductor-semiconductor hybrid systems is pivotal to realizing the promise of topological quantum computat…
Reply to the Comment by Tikhonov and Khrapai on "Long-range crossed Andreev reflection in a topological insulator nanowire proximitized by a superconductor"
Junya Feng, Henry F. Legg, Mahasweta Bagchi +3
The comment (arXiv:2505.23490) fails to identify any scientific errors and its central arguments actually support the main conclusions of our publication [Nat. Phys. 21, 708 (2025)…
Tunable superconducting diode effect in a topological nano-SQUID
Ella Nikodem, Jakob Schluck, Max Geier +6
A Josephson diode passes current with zero resistance in one direction but is resistive in the other direction. While such an effect has been observed in several platforms, a large…
