Tuning the Josephson diode response with an ac current

R Seoane Souto, M Leijnse, C Schrade, M Valentini… - Physical Review …, 2024 - APS
Josephson diodes are superconducting elements that show an asymmetry in the critical
current depending on the direction of the current. Here, we theoretically explore how an …
