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…
Probing Fermi-surface spin-textures via the nonlinear Shubnikov-de Haas effect
Kazuki Nakazawa, Henry F. Legg, Renato M. A. Dantas +2
The coupling of spin and electronic degrees of freedom via the spin-orbit interaction (SOI) is an essential ingredient for many proposed future technologies. However, probing the s…
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)…
Anomalous Josephson effect in hybrid superconductor-hole systems
Peter D. Johannsen, Henry F. Legg, Stefano Bosco +2
We consider hybrid systems consisting of a hole-doped semiconductor coupled to electronic states of finite-size superconductors, where the opposite sign of the masses in the two su…
Properties and prevalence of false poor man's Majoranas in two- and three-site artificial Kitaev chains
Melina Luethi, Henry F. Legg, Daniel Loss +1
It was predicted that a minimal chain of two quantum dots (QDs) connected via a superconductor can host perfectly localized zero-energy states, known as poor man's Majoranas (PMMs)…
Comment on "Interferometric single-shot parity measurement in InAs-Al hybrid devices", Microsoft Quantum, Nature 638, 651-655 (2025)
Henry F. Legg
We consider the 'parity readout' of a (topological) superconductor claimed in Nature 638, 651-655 (2025). A prerequisite for this claim is the existence of a superconducting gap in…
