abstract = {Spin waves in antiferromagnetic materials have great
potential for next-generation magnonic technologies.
However, their properties and their dependence on the type
of ground-state antiferromagnetic structure are still open
questions. Here, we investigate theoretically spin waves in
one- and two-dimensional model systems with a focus on
noncollinear antiferromagnetic textures such as spin spirals
and skyrmions of opposite topological charges. We address in
particular the nonreciprocal spin excitations recently
measured in bulk antiferromagnet α−Cu2V2O7 utilizing
inelastic neutron scattering experiments [Phys. Rev. Lett.
119, 047201 (2017)], where we help to characterize the
nature of the detected spin-wave modes. Furthermore, we
discuss how the Dzyaloshinskii-Moriya interaction can lift
the degeneracy of the spin-wave modes in antiferromagnets,
resembling the electronic Rashba splitting. We consider the
spin-wave excitations in antiferromagnetic spin-spiral and
skyrmion systems and discuss the features of their inelastic
scattering spectra. We demonstrate that antiskyrmions can be
obtained with an isotropic Dzyaloshinskii-Moriya interaction
in certain antiferromagnets.},
