Title: Topological Magnons
Abstract: I give an overview of the insights we and other people have had into the band topology of magnons and discuss in some detail three main topics from our work: (i) Neutron scattering intensity around magnon touching points, (ii) the non-Hermitian topology of spontaneous magnon decay and (iii) connections to experiment.
Preprint – Dirac magnons. Paper “Non-Hermitian topology of spontaneous magnon decay”.
