Disorder induces transitions from π to 0 phases in altermagnetic Josephson junctions, suppresses critical current, and destabilizes the φ phase in a nonreciprocal way.
Here, thew 0 r term indicates the usual nonmagnetic type disorder, and thewx r σx and wy r σy terms are magnetic disorder that couples spin degrees of freedom in AMs

Disorder-Induced Phase Transitions in Altermagnetic Josephson Junctions
Disorder induces transitions from π to 0 phases in altermagnetic Josephson junctions, suppresses critical current, and destabilizes the φ phase in a nonreciprocal way.
