# QM3 Matéria Quântica & Matemática

### Topological Magnons

I give an overview of the insights we and other people have had into the band structure of magnons and discuss in some detail three main topics from our work: (i) the robustness of topological edge states in the presence of magnon interactions (ii) visualization of spin-momentum locking in magnon systems (iii) the non-Hermitian topology of spontaneous magnon decay.

O objectivo principal do $QM^3$ consiste em discutir tópicos recentes em física quântica do ponto de vista da matemática e promover pontes entre as comunidades física e matemática.
