Topological superconductivity mediated by magnons of helical magnetic states

K Mæland, S Abnar, J Benestad, A Sudbø - Physical Review B, 2023 - APS
We recently showed that spin fluctuations of noncoplanar magnetic states can induce
topological superconductivity in an adjacent normal metal [Mæland, Phys. Rev. Lett. 130 …

Many-body effects and topology in magnets and superconductors
