Often the concept of anyons is introduced as if a generalization of perturbative quanta like fundamental bosons and fermions. But many (concepts of) types of anyons are really solitonicdefects such as vortices.
The general concept of braiding of defects in solid state physics:

(including a review of basic homotopy theory)
and more specifically for vortices:
Explicit discussion in terms of anyons:
Alexei Kitaev, Anyons in an exactly solved model and beyond, Annals of Physics 321 1 (2006) 2-111 doi:10.1016/j.aop.2005.10.005
Anyonic particles are best viewed as a kind of topological defects that reveal nontrivial properties of the ground state. p. 4

and in (other) superfluids:
and in condensates of non-defect anyons:
See also Ahn, Park & Yang 19 who refer to the band nodes in the Brillouin torus of a semi-metal as “vortices in momentum space”.
And see at defect brane.
