Scattering of high-energy magnons off a magnetic skyrmion
We discuss the scattering of high-energy magnons off a single magnetic skyrmion within the field-polarized
 ground state of a two-dimensional chiral magnet. For wavevectors larger than the inverse skyrmion radius,krs>>1 the magnon scattering is dominated by an emerging magnetic field w...

| description | We discuss the scattering of high-energy magnons off a single magnetic skyrmion within the field-polarized
ground state of a two-dimensional chiral magnet. For wavevectors larger than the inverse skyrmion radius,krs>>1 the magnon scattering is dominated by an emerging magnetic field whose flux density is essentially determined
by the topological charge density of the skyrmion texture. This leads to skew and rainbow scattering
characterized by an asymmetric and oscillating differential cross section. We demonstrate that the transversal
momentum transfer to the skyrmion is universal due to the quantization of the total emerging flux while the longitudinal
momentum transfer is negligible in the high-energy limit. This results in a magnon-driven skyrmion
motion approximately antiparallel to the incoming magnon current and a universal relation between current and
skyrmion-velocity.
