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…

Coherent microwave comb generation via the Josephson effect
Angelo Greco, Xavier Ballu, Francesco Giazotto +1
Frequency combs represent exceptionally precise measurement tools due to the coherence of their spectral lines. While optical frequency comb sources constitute a well-established t…

Supercurrent Noise in a Phase-Biased Superconductor-Normal Ring in Thermal Equilibrium
Ziwei Dou, Xavier Ballu, Quan Dong +6
In superconductor-normal-superconductor (SNS) junctions, dissipationless supercurrent is mediated via Andreev bound states (ABSs) controlled by the phase difference between the two…
