Correlation Effects in Quantum Spin Hall Insulators — •Martin Hohenadler — Theoretische Physik I, Universität Würzburg, 97074 Würzburg, Germany

Time-reversal invariant insulating states with topological properties, including topological insulators, have been in the focus of research in recent years. On the theoretical side, electronic correlation effects are of particular interest, as they can both destroy and create topological phases. This talk gives an overview of research on two-dimensional, correlated topological insulators, with a focus on quantum Monte Carlo results for the Kane-Mele-Hubbard model.
