abstract = {The multiferroic ferrimagnet Cu2OSeO3 with a chiral crystal
structure has attracted a lot of recent attention due to the
emergence of a magnetic skyrmion order in this material.
Here, the topological properties of its magnon excitations
are systematically investigated by linear spin-wave theory
and inelastic neutron scattering. When considering
Heisenberg exchange interactions only, two degenerate Weyl
magnon nodes with topological charges ±2 are observed at
high-symmetry points. Each Weyl point splits into two as the
symmetry of the system is further reduced by including into
consideration the nearest-neighbor Dzyaloshinskii-Moriya
interaction, crucial for obtaining an accurate fit to the
experimental spin-wave spectrum. Also, one additional pair
of Weyl points appears near the R point. The predicted
topological properties are verified by surface state and
Chern number analysis. Additionally, we predict that a
measurable thermal Hall conductivity can be associated with
the emergence of the Weyl points, the position and number of
which can be tuned by modifying the Dzyaloshinskii-Moriya
interaction in the system.},
