We consider the Kane-Mele-Hubbard model with a magnetic π flux threading each honeycomb plaquette. The resulting model has remarkably rich physical properties. In each spin sector, the noninteracting band structure is characterized by a total Chern number C = ±2. Fine-tuning of the intrinsic spin-orbit coupling λ leads to a quadratic band crossing point associated with a topological phase trans...
