The discovery of the quantum spin Hall effect and topological insulators more than a decade
ago has revolutionized modern condensed matter physics. Today, the field of topological …

We determine the phase diagram of the Kane-Mele model with a long-range Coulomb
interaction using an exact quantum Monte Carlo method. Long-range interactions are …

We study a one-dimensional model of interacting bosons coupled to a dynamical Z 2 field,
the Z 2 Bose-Hubbard model, and analyze the interplay between spontaneous symmetry …
