Gate-Assisted Phase Fluctuations in All-Metallic Josephson Junctions
Julien Basset, Ognjen Stanisavljević, Marko Kuzmanović +4
The discovery that a gate electrode suppresses the supercurrent in purely metallic systems is missing a complete physical understanding of the mechanisms at play. We here study the…
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…
Nonadiabatic Dynamics of Strongly Driven Diffusive Josephson Junctions
Julien Basset, Marko Kuzmanović, Pauli Virtanen +5
By measuring the Josephson emission of a diffusive Superconductor-Normal metal-Superconductor (SNS) junction at a finite temperature we reveal a non-trivial sensitivity of the supe…
High Kinetic Inductance Microwave Resonators Made by He-Beam Assisted Deposition of Tungsten Nanowires
Julien Basset, Diana Watfa, Gianluca Aiello +9
We evaluate the performance of hybrid microwave resonators made by combining sputtered Nb thin films with Tungsten nanowires grown with a He-beam induced deposition technique. Depe…
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…
