Long- to short-junction crossover and field-reentrant critical current in Al/Ag-nanowires/Al Josephson junctions
A. Murani, S. Sengupta, A. Kasumov +5
We have probed the superconducting proximity effect through long high-quality monocrystalline Ag nanowires, by realizing Josephson junctions of different lengths, with different su…
Absence of a dissipative quantum phase transition in Josephson junctions
Anil Murani, Nicolas Bourlet, Hélène le Sueur +7
Half a century after its discovery, the Josephson junction has become the most important nonlinear quantum electronic component at our disposal. It has helped reshape the SI system…
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…
Coherence-enhanced, phase-dependent dissipation in long SNS Josephson junctions: revealing Andreev Bound States dynamics
Bastien Dassonneville, Anil Murani, Meydi Ferrier +2
One of the best known causes of dissipation in ac driven quantum systems stems from photon absorption. Dissipation can also be caused by the retarded response to the time-dependent…
Andreev spectrum with high spin-orbit interactions: revealing spin splitting and topologically protected crossings
Anil Murani, Alexei Chepelianskii, Sophie Guéron +1
We investigate numerically the Andreev spectrum of a multichannel mesoscopic quantum wire (N) with high spin-orbit interaction coupled to superconducting electrodes (S), contrastin…
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…
Magnetic field resistant quantum interferences in bismuth nanowires based Josephson junctions
Chuan Li, A. Kasumov, A. Murani +11
We investigate proximity induced superconductivity in micrometer-long bismuth nanowires con- nected to superconducting electrodes with a high critical field. At low temperature we…
