Flux-tunable global and local superconductivity in a topological insulator nano-SQUID
Ella Nikodem, Jakob Schluck, Michał Papaj +5
Topological systems are defined by global properties that enforce the existence of local boundary modes. Three-dimensional topological insulators (TIs) were among the earliest prop…
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)…
Quasiparticle interference on the surface of BiSe terminated (PbSe)(BiSe)
Mahasweta Bagchi, Philipp Rüßmann, Gustav Bihlmayer +3
Among the family of topological superconductors derived from {\BiSe}, is unique in its surface termination of…
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…
Topological Insulator nano-SQUID: Flux-tunable platform for topological superconductivity
Ella Nikodem, Jakob Schluck, Henry F. Legg +5
Many efforts have been made in the past decade to realize topological superconductivity using superconducting proximity effect, but an ideal platform is still lacking. A 3D topolog…
Characterizing the chemical potential disorder in the topological insulator (BiSb)Te thin films
Jens Brede, Mahasweta Bagchi, Adrian Greichgauer +6
We use scanning tunneling microscopy and spectroscopy under ultra-high vacuum and down to 1.7 K to study the local variations of the chemical potential on the surface of the topolo…
