Two-dimensional altermagnets: Superconductivity in a minimal microscopic model
Bjørnulf Brekke, Arne Brataas, Asle Sudbø
We propose a minimal toy model for a two-dimensional altermagnet. The model unravels altermagnetic properties at a microscopic level. We find spin-split electron- and non-degenerat…

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…
