Interacting Topological Insulators — •Stephan Rachel — Institut für Theoretische Physik, Technische Universität Dresden

The physics of electronic correlations in systems with topological band structures is a young and exciting field. In this talk, I will give an overview of the most relevant and interesting interaction effects in 2D and 3D topological insulators. Specifically, I will address the physics of the Kane-Mele-Hubbard model, the prototypical model of a correlated topological insulator, and its descendants in 2D as well as topological Mott insulators emerging in 3D topological band structures. Eventually, I will explain how strong interactions can affect the surface states of strong topological insulators and lead to even more exotic phases.
