In this paper we study two models of symmetry-breaking topological insulators. They are the variants of the d-density wave Hamiltonian proposed by Chakravarty, Laughlin, Morr and Nyack[1] to explain the pseudogap of the cuprates. After doping, both models exhibit an anomalous thermal Hall effect similar to that reported in Ref.[2]. Moreover, they also possess hole pockets centered along the Brillouin zone diagonals consistent with the Hall coefficient measured in Ref.[3].
