Graphene Josephson diodes from inherent asymmetric disorder
Ivan Villani, Luca Chirolli, Matteo Carrega +10
Josephson diodes are non-reciprocal superconducting devices characterized by different switching currents depending on the current flow direction. They recently attracted considera…
Magnetically Induced Switching-Current Jumps in InAs/Al Josephson Junctions
Ofelia Durante, Roberta Citro, Elia Strambini +8
We report Barkhausen-like switching at millitesla fields in an -doped InAs/Al nanowire Josephson junction, which serves as an interferometric probe of intrinsic magnetic reconfi…
Impact of magnetic field direction on anti-dot-based superconducting diodes
E. B. de Melo Junior, E. Strambini, F. Giazotto +1
The superconducting diode effect (SDE) is a fundamental building block for dissipationless nonreciprocal electronics, yet its microscopic origins in thin films often involve compet…
Diode effect in the Fraunhofer pattern of disordered planar Josephson junctions
Luca Chirolli, Angelo Greco, Alessandro Crippa +4
The Josephson diode effect describes the property of a Josephson junction to have different values of the critical current for different direction of applied bias current and it is…
Supercurrent diode with high winding vortex
Yuri Fukaya, Maria Teresa Mercaldo, Daniel Margineda +5
Nonreciprocal supercurrent refers to the phenomenon where the maximum dissipationless current in a superconductor depends on its direction of flow. This asymmetry underlies the ope…
Biharmonic-Drive Tunable Josephson Diode
L. Borgongino, R. Seoane Souto, A. Paghi +6
The superconducting diode effect has garnered significant interest due to its prospective applications in cryogenic electronics and computing, enabling directional supercurrent tra…
