Many-body effects on superconductivity mediated by double-magnon processes in altermagnets

Kristian Mæland, Bjørnulf Brekke, Asle Sudbø

Altermagnets exhibit a large electron spin splitting which can be understood as a result of strong coupling between itinerant electrons and localized spins. We consider superconduc…
