Surface excitations of 3d Topological Insulators: conformal invariance, self-duality and bosonization |
|
Résumé |
Massless fermions and anyons on the surface of (3 1)-dimensional topological insulators can be described at the semiclassical level by a non-local Abelian gauge theory involving two gauge fields. The theory is non-trivial owing to its solitonic excitations with electric and magnetic charges. We compute the partition function and the solitonic spectrum, thus showing conformal invariance and electric-magnetic self-duality. This theory also provides a framework for semiclassical bosonization of (2 1)d fermions.
