Probing the topological protection of edge states in multilayer tungsten ditelluride with the superconducting proximity effect
X. Ballu, Z. Dou, L. Bugaud +9
The topology of WTe2, a transition metal dichalcogenide with large spin-orbit interactions, is thought to combine type II Weyl semimetal and second-order topological insulator (SOT…
Long-lived Andreev states as evidence for protected hinge modes in a bismuth nanoring Josephson junction
A. Bernard, Y. Peng, A. Kasumov +9
Second-order topological insulators are characterized by helical, non-spin-degenerate, one-dimensional states running along opposite crystal hinges, with no backscattering. Injecti…
Spin-orbit-enhanced robustness of supercurrent in graphene/WS Josephson junctions
T. Wakamura, N. J. Wu, A. D. Chepelianskii +7
We demonstrate enhanced robustness of the supercurrent through graphene-based Josephson junctions in which strong spin-orbit interactions (SOIs) are induced. We compare the persist…
Microwave signature of robust topological Andreev-level crossings in superconducting proximitized crystalline Bi nanowires
A. Murani, B. Dassonneville, A. Kasumov +5
Demonstrating the topological protection of Andreev states in Josephson junctions is an experimental challenge. In particular the telltale periodicity expected for the current…
Ballistic edge states in Bismuth nanowires revealed by SQUID interferometry
Anil Murani, Alik Kasumov, Shamashis Sengupta +9
Spin-orbit interactions are known to have drastic effects on the band structure of heavy-element-based materials. Celebrated examples are the recently identified 3D and 2D topologi…
Full range of proximity effect probed with Superconductor/Graphene/Superconductor junctions
Chuan Li, S. Guéron, A. Chepelianskii +1
The high tunability of the density of states of graphene makes it an ideal probe of quantum transport in different regimes. In particular, the supercurrent that can flow through a…
