Cluster multipole dynamics in noncollinear antiferromagnets
A systematic framework to investigate the spin dynamics in a noncollinear antiferromagnet is proposed. Taking Mn_{3}Sn as a representative example, we derive an effective low-energy model based on the multipole expansion of the magnetic structure, and investigate the uniform precession and the domai...
