Strong correlations in a Josephson junction with odd electrons spontaneously break symmetries to enable zero-field Josephson diode effect without magnetic order.
Here, we use supercurrent diode effect (SDE) for both without distinction, given the profound similarity under interchange of Cooper pair momentum qand Josephson phaseϕ
