Strong correlations in a Josephson junction with odd electrons spontaneously break symmetries to enable zero-field Josephson diode effect without magnetic order.
[59] to call a Josephson junction with double energy mimina atϕ=±φaφ- junction, while that with a single minimum atϕ=φ 0 ̸= 0 orπaφ 0-junction
