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…

Sub-gap states in semiconducting-superconducting nanowire hybrid devices are controversially discussed as potential topologically non-trivial quantum states. One source of ambiguit…
Quantum noise in carbon nanotubes as a probe of correlations in the Kondo regime
Meydi Ferrier, Raphaëlle Delagrange, Julien Basset +9
Most of the time, electronic excitations in mesoscopic conductors are well described, around equilibrium, by non-interacting Landau quasi-particles. This allows a good understandin…
