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…
Long-range crossed Andreev reflection in topological insulator nanowires proximitized by a superconductor
Junya Feng, Henry F. Legg, Mahasweta Bagchi +3
Crossed Andreev reflection (CAR) is a nonlocal transport phenomenon that creates/detects Cooper-pair correlations between distant places. It is also the basis of Cooper-pair splitt…
Universal Role of Combined Symmetry for the Protection of the Dirac Cone in Antiferromagnetic Topological Insulators
Asuka Honma, Noriyuki Kabeya, Seigo Souma +13
Antiferromagnetic topological insulators (AF TIs) are predicted to exhibit exotic physical properties such as gigantic optical and topological magnetoelectric responses. While a ke…
Robust gap closing and reopening in topological-insulator Josephson junctions
Jakob Schluck, Ella Nikodem, Anton Montag +4
In the seminal proposal by Fu and Kane, the superconducting proximity effect is used to realize topological superconductivity in the topological surface state (TSS) of a 3D topolog…
Phonon thermal Hall effect in charge-compensated topological insulators
Rohit Sharma, Mahasweta Bagchi, Yongjian Wang +2
From a systematic study of thermal and charge transport in various single crystals of compensated topological insulators we identify the evolution of a large low-temperature therma…
Antiferromagnetic topological insulator with selectively gapped Dirac cones
A. Honma, D. Takane, S. Souma +14
Antiferromagnetic (AF) topological materials offer a fertile ground to explore a variety of quantum phenomena such as axion magnetoelectric dynamics and chiral Majorana fermions. T…
Topological Insulators
Yoichi Ando
Topological insulators are characterized by insulating bulk and conducting surface, the latter is a necessity consequence of the nontrivial topology of the wavefunctions forming th…
Direct Observation of Nonequivalent Fermi-Arc States of Opposite Surfaces in Noncentrosymmetric Weyl Semimetal NbP
S. Souma, Zhiwei Wang, H. Kotaka +9
We have performed high-resolution angle-resolved photoemission spectroscopy (ARPES) on noncentrosymmetric Weyl semimetal candidate NbP, and determined the electronic states of both…
