Spin Inertia as a Source of Topological Magnons: Chiral Edge States from Coupled Precession and Nutation

Subhadip Ghosh, Mikhail Cherkasskii, Ritwik Mondal +2

Spin inertia has been demonstrated to give rise to high-frequency nutational excitations beyond the conventional low-frequency precessional modes. Here, we demonstrate that the hyb…
