Title: Self-dual Conformal Theory on the Surface of Topological Insulators
Abstract: The non-local Abelian gauge theory in (2+1) dimensions provides a bosonic description of massless fermions and anyons on the surface of (3+1)-dimensional topological insulators. The theory is non-trivial owing to its solitonic excitations with electric and magnetic charges. Upon rewriting it into a local theory in one extra dimension, we compute the partition function and the solitonic spectrum, thus showing conformal invariance and electric-magnetic self-duality.
