Completing our investigation of magnon band-sticking in a non-symmorphic crystal
The combination of a non-symmorphic and time-reversal symmetry in a material can lead to nodal planes, planar band degeneracies (so-called "band-sticking") at the boundary of the Brillouin zone. Similar to point-like degeneracies, these nodal planes can be assigned topological invariants and will lead to protected surface states. An external magnetic field allows to break time-reversal symmetry, allowing to lift the nodal plane degeneracy and thereby adjust the material¿s topological properties in a controlled way. We wish to finish our investigation into field-polarised magnon band degeneracies in the skyrmion host Cu2OSeO3, for which we already have a working theoretical spin-wave model and almost full experimental data, but still need to resolve anomalies discovered during a previous experiment. (Note that Niclas Heinsdorf (MPG, Germany), Andreas Schnyder (MGP, Germany), and Marc Wilde (TUM, Germany) are also co-proposers, but were not listed in the user database.)
