Chirality-Driven Orbital Angular Momentum and Circular Dichroism in CoSi
Stefanie Suzanne Brinkman, Xin Liang Tan, Bjørnulf Brekke +15
Chiral crystals and molecules were recently predicted to form an intriguing platform for unconventional orbital physics. Here, we report the observation of chirality-driven orbital…
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…
Interfacial Magnon-Mediated Superconductivity in Twisted Bilayer Graphene
Bjørnulf Brekke, Asle Sudbø, Arne Brataas
The interfacial coupling between electrons and magnons in adjacent layers can mediate an attractive electron-electron interaction and induce superconductivity. We consider magic-an…
