      abstract     = {The phase of the quantum-mechanical wave function can
                      encode a topological structure with wide-ranging physical
                      consequences, such as anomalous transport effects and the
                      existence of edge states robust against perturbations. While
                      this has been exhaustively demonstrated for electrons,
                      properties associated with the elementary quasiparticles in
                      magnetic materials are still underexplored. Here, we show
                      theoretically and via inelastic neutron scattering
                      experiments that the bulk ferromagnet Mn5Ge3 hosts gapped
                      topological Dirac magnons. Although inversion symmetry
                      prohibits a net Dzyaloshinskii-Moriya interaction in the
                      unit cell, it is locally allowed and is responsible for the
                      gap opening in the magnon spectrum. This gap is predicted
                      and experimentally verified to close by rotating the
                      magnetization away from the c-axis with an applied magnetic
                      field. Hence, Mn5Ge3 realizes a gapped Dirac magnon material
                      in three dimensions. Its tunability by chemical doping or by
                      thin film nanostructuring defines an exciting new platform
                      to explore and design topological magnons. More generally,
                      our experimental route to verify and control the topological
                      character of the magnons is applicable to bulk
                      centrosymmetric hexagonal materials, which calls for
                      systematic investigation.},
