Topological Mott Insulators and Discontinuous -Terms
Michael A. DeMarco, Ethan Lake, Xiao-Gang Wen
We introduce a lattice field theory that describes the transition between a superfluid (SF) and a bosonic topological Mott Insulator (tMI) -- a symmetry protected topologica…

A Commuting Projector Model with a Non-zero Quantized Hall conductance
Michael DeMarco, Xiao-Gang Wen
By ungauging a recently discovered lattice rotor model for Chern-Simons theory, we create an exactly soluble path integral on spacetime lattice for Symmetry Protected Topo…
