Abstract
We study the emergence of gauge couplings in the surface states of topological insulators. We show that gauge fields arise when a three dimensional strong topological insulator is coated with an easy-plane ferromagnet with magnetization parallel to the surface. We analyze the modification induced by the gauge fields on the surface spectrum for some specific magnetic configurations.
