Topological Invariant and Quantum Spin Models from Magnetic π Fluxes in Correlated Topological Insulators
The adiabatic insertion of a π flux into a quantum spin Hall insulator gives rise to localized spin and charge fluxon states. We demonstrate that π fluxes can be used in exact quantum Monte Carlo simulations to identify a correlated Z_{2} topological insulator using the example of the Kane-Mele-Hubb...
