Chiral split magnons in metallic g-wave altermagnets: Insights from many-body perturbation theory

Wejdan Beida, Ersoy Sasioglu, Christoph Friedrich +3

Altermagnets are a novel class of magnetic materials that bridge the gap between ferromagnets (FMs) and antiferromagnets (AFMs). A key feature is the non-degeneracy of magnon modes…
