Band Topology in Quantum Magnets: From nontrivial excitations to non-Hermitian topology and spintronics

International Focus Workshop
13 - 15 June 2022

This three day focus workshop is the first meeting dedicated to topological magnetic excitations. This relatively young field connects to various topics in contemporary condensed matter including quantum magnetism, spintronics, non-Hermitian topology, the dynamics of complex spin textures, and electronic topological materials coupled to magnetism.

Topics include

Theoretical advances in magnon band-topology:

  • Novel response functions arising from nontrivial magnon bands
  • Symmetry classification of topological magnon bands
  • Necessary conditions for nontrivial magnon topology
  • Magnon-magnon interaction and non-Hermitian topological band structures
  • Non-Hermitian bulk-boundary correspondence


Magnon band-topology in experiments:

  • Hall transport of magnetic excitations
  • Hybridization of magnons with photons and phonons
  • Direct detection of magnon boundary modes
  • Nontrivial band topology in skyrmion systems
  • Connections with spintronics and spin-current-based technologies

The call for applications is closed.

We plan for a hybrid workshop with a number of participants on-site and the others connected remotely.
Online attendance will be possible in any case. The organizers will inform about an option of on-site attendance at a later stage.

For on-site participation the registration fee is 140 Euro; costs for accommodation and meals will be covered by the Max Planck Institute.
Limited funding is available to partially cover travel expenses.

No fee for remote participation.


Scientific Program

The scientific program of the workshop will be available by end of May 2022
