Defect anyons

Defect anyons

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 solitonic\;defects such as vortices.

The general concept of braiding of defects in solid state physics:

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]]

Concrete vortex\;anyons in Bose-Einstein condensates:

and in (other) superfluids:

  • Yusuke Masaki, Takeshi Mizushima, Muneto Nitta, Non-Abelian Half-Quantum Vortices in 3P2 Topological Superfluids [[arXiv:2107.02448]]

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.
