Description
We discuss solitonic field configurations on a spherical magnet. Exploiting
the Hamiltonian structure and concepts of angular momentum, we present a new family of
localized solutions to the Landau-Lifshitz equation that are topologically distinct
from the ground state and break rotational symmetry. The approach illustrates emergent
spin-orbit coupling arising from the loss of individual rotational invariance in spin
and coordinate space---a common feature of condensed matter systems with topological
phases.
