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…
Higher-Order Topology in Bismuth
Frank Schindler, Zhijun Wang, Maia G. Vergniory +12
The mathematical field of topology has become a framework to describe the low-energy electronic structure of crystalline solids. A typical feature of a bulk insulating three-dimens…
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…
