      abstract     = {The discovery of topological states of matter has led to a
                      revolution in condensed-matter science. While a non-trivial
                      band topology in a material is often associated with
                      intriguing transport properties, much less attention has
                      been given to the impact on spin dynamics and
                      non-equilibrium magnetization states. Here, we provide
                      evidence that a chiral asymmetric magnon dispersion in the
                      two-dimensional Weyl magnet Fe/W(110) is related to the
                      presence of Weyl fermions close to the Fermi energy and
                      surface Fermi arcs. We find that the large anomalous Hall
                      conductivity and the Dzyaloshinskii–Moriya interaction are
                      attributed to the non-trivial band topology in the composite
                      momentum-magnetization space. Our results show the direct
                      impact of Weyl fermions on both the charge and spin dynamics
                      in a two-dimensional magnet. Unveiling these principles can
                      promote innovative technologies in magnonics by utilizing
                      topological materials, where magnons and non-trivial
                      topological electronic states can be manipulated through
                      magnetization.},
