Author(s): Zohar Ringel and Ady Stern We study the edge and surface theories of topological insulators from the perspective of anomalies and identify a Z 2 anomaly associated with charge conservation. The anomaly is manifested through a two-point correlation function involving creation and annihilation operators on two decoupled boundari... [Phys. Rev. B 88, 115307] Published Tue Sep 17, 2013
