Supercurrent rectification and magnetochiral effects in symmetric Josephson junctions

C Baumgartner, L Fuchs, A Costa, S Reinhardt… - Nature …, 2022‏ - nature.com
Transport is non-reciprocal when not only the sign, but also the absolute value of the current
depends on the polarity of the applied voltage. It requires simultaneously broken inversion …

Universal Josephson diode effect

M Davydova, S Prembabu, L Fu - Science advances, 2022‏ - science.org
We propose a universal mechanism for the Josephson diode effect in short Josephson
