Magnon-cooparons in magnet-superconductor hybrids
Abstract
Magnet-superconductor heterostructures provide a means to engineer unconventional spin-triplet Cooper pairs using ordinary superconductors. Here, a magnet-superconductor bilayer is predicted to host a composite quasiparticle consisting of spinful Cooper pairs coupled to a magnon excitation.
