Hierarchical quasiparticle dynamics in antiferromagnets revealed by time- and momentum-resolved X-ray scattering

Abstract Energy flows among coupled subsystems are essential for ultrafast dynamics and high-speed technologies. In magnetic materials, spin fluctuations —magnons— mediate these flows in ultrafast magnetism. Yet momentum-resolved access to low-energy magnons governing the microsc...
