Anomalous supercurrent and diode effect in locally perturbed topological Josephson junctions
Samuele Fracassi, Simone Traverso, Niccolò Traverso Ziani +3
The simultaneous breaking of time-reversal and inversion symmetry can lead to peculiar effects in Josephson junctions, such as the anomalous Josephson effect or supercurrent rectif…
Half-integer Shapiro steps in highly transmissive InSb nanoflag Josephson junctions
Andrea Iorio, Alessandro Crippa, Bianca Turini +8
We investigate a ballistic InSb nanoflag-based Josephson junction with Nb superconducting contacts. The high transparency of the superconductor-semiconductor interfaces enables the…
Josephson Diode Effect in High Mobility InSb Nanoflags
Bianca Turini, Sedighe Salimian, Matteo Carrega +6
We report evidence of non-reciprocal dissipation-less transport in single ballistic InSb nanoflag Josephson junctions, owing to a strong spin-orbit coupling. Applying an in-plane m…
Thermodynamics of a phase-driven proximity Josephson junction
Francesco Vischi, Matteo Carrega, Alessandro Braggio +2
We study the thermodynamic properties of a superconductor/normal metal/superconductor Josephson junction {in the short limit}. Owing to the proximity effect, such a junction consti…
Quasiparticle entropy in superconductor/normal metal/superconductor proximity junctions in the diffusive limit
Pauli Virtanen, Francesco Vischi, Elia Strambini +2
We discuss the quasiparticle entropy and heat capacity of a dirty superconductor-normal metal-superconductor junction. In the case of short junctions, the inverse proximity effect…
