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…
Multiplexed microwave resonators by frequency comb spectroscopy
Angelo Greco, Jukka-Pekka Kaikkonen, Luca Chirolli +4
Coplanar waveguide resonators are central to the thriving field of circuit quantum electrodynamics. Recently, we have demonstrated the generation of a broadband microwave-frequency…
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…
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…
Quasi--periodic supercurrent at quantum Hall transitions
Ivan Villani, Matteo Carrega, Alessandro Crippa +9
The combination of superconductivity and quantum Hall (QH) effect is regarded as a key milestone in advancing topological quantum computation in solid-state systems. Recent quantum…
