Query: Electrically Active Domain Wall Magnons in Layered van der Waals
  Antiferromagnets   We study theoretically domain wall (DW) magnons-elementary collective
excitations of magnetic DWs -- in easy-axis layered van der Waals (vdW)
antiferromagnets, where they behave as normal modes of coupled spin
superfluids. We uncover that, due to spin-charge coupling in vdW magnets, such
DW magnons can be activated by voltage-induced torques, thereby providing a
path for their low-dissipation and nanoscale excitation. Moreover, the
electrical activation and the number of DW magnons at a frequency can be
controlled by applying symmetry-breaking static magnetic field, adding
tunability of signal transmission by them. Our results highlight that domain
walls in vdW magnets provide a promising platform to route coherent spin
information for a broad range of explorations in spintronics and magnetism.
