Hamburg Photon Science Colloquium | Topological magnon states & orbital magnetic moment of magnons

by Ingrid Mertig (Martin Luther University Halle-Wittenberg, Germany)

Friday 23 Oct 2020, 14:00 → 15:30 Europe/Berlin

We discover that magnons, the quasipar ticles of magnetically ordered materials, carry certain topological properties and magnetic moment beyond their spin magnetic moment. Our rigorous quantum theor y uncovers the existing topological states and a magnonic orbital magnetic moment brought about by spin-orbit coupling. We propose experimental hallmarks of the topological properties and the orbital moment and conclude that its signatures are within reach of today’s experiments.
