Title: Magnon Spectrum around Skyrmions in Frustrated Magnets
Abstract: Magnetic skyrmions are topologically nontrivial spin textures typically studied in chiral magnets. We consider isolated skyrmions and skyrmion lattices in frustrated magnets, investigating their dynamics via their magnon spectra. The ‘helicity’ zero mode in these systems hybridizes with magnon modes, and gives rise to a new band in lattices. Magnetic fluctuations around skyrmions introduce new helicity-based modes around interacting skyrmions, and strongly affect magnon propagation in lattices.
