A relationship between nonunitary mixed parity superconductivity and magnetism with spin-orbit coupling

Abstract
We show that Hamiltonian for nonunitary mixed parity superconductivity can be recast into that for magnetism with spin-orbit coupling by the Schrieffer-Wolff transformation, indicating that nonunitary mixed parity superconductivity and magnetism with spin-orbit coupling can share the same physics. As demonstrations, we discuss the Dzyaloshinskii-Moriya type interactions, magnetoelectric effect, supercurrent-induced spin current, and altermagnetism in nonunitary mixed parity superconductors. All these effects originate purely from superconductivity, without any magnetism and spin-orbit coupling.
