Topological Insulators (TIs)  are insulators in the bulk, but have exotic metallic states at their surfaces. The topology, associated with the electronic wavefunctions of these systems, changes when passing from the bulk to the surface.This work studies, by means of infrared spectroscopy, the low en...
