We theoretically show, in a twisted junction of superconducting atomic layers, that momentum conservation allows Cooper-pair tunneling only at commensurate twist angles when the pair has a nonzero total momentum as suggested by a recent experimental study of superconductivity in multilayer rhombohedral graphene.
