A Holographic Fractional Topological Insulator

arXiv:1007.3253 · doi:10.1103/PhysRevD.82.086001

Abstract

We give a holographic realization of the recently proposed low energy effective action describing a fractional topological insulator. In particular we verify that the surface of this hypothetical material supports a fractional quantum Hall current corresponding to half that of a Laughlin state.
