Phase-dependent dissipation and supercurrent of a graphene-superconductor ring under microwave irradiation
Ziwei Dou, Taro Wakamura, Pauli Virtanen +8
A junction with two superconductors coupled by a normal metal hosts Andreev bound states whose energy spectrum is phase-dependent and exhibits a minigap, resulting in a periodic su…
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…
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…
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…
Magnetic field anti-symmetry of photovoltaic voltage in evanescent microwave fields
A. Chepelianskii, S. Guéron, F. Pierre +3
A two dimensional electron system without spatial inversion symmetry develops a sample specific dc voltage when exposed to a microwave radiation at low temperature. We investigate…
Effects of Spin-Orbit Interactions on Tunneling via Discrete Energy Levels in Metal Nanoparticles
D. G. Salinas, S. Guéron, D. C. Ralph +2
The presence of spin-orbit scattering within an aluminum nanoparticle affects measurements of the discrete energy levels within the particle by (1) reducing the effective g-factor…
