Title:
Surface Excitations of 3d Topological Insulators: Conformal Invariance, Self-Duality and Bosonization

Speaker:
Andrea Cappelli

Abstract:
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
