Spin waves scattering on a Bloch point
arXiv:1411.5096 · doi:10.1103/PhysRevB.90.224414
Abstract
We show that, after a transformation, the dynamics of linear perturbations (spin waves) around a singular Bloch point soliton is formally equivalent to a quantum system of an electron in a magnetic monopole field. The analytical solution to this problem is known and allows us to find the spectrum and the scattering of a wave in a Bloch point field.
