Inspired by Kitaev's periodic table, we will show some mathematical models of topological insulators.
The essential aspects of such models, based on magnetic Schrödinger operators, is the presence of non-trivial topological indices (e.g. Chern number, Fu-Kane-Mele index,…) and, correspondingly, delocalization of electronic states and, on the phenomenological side, dissipationless quantum transport.
The approach in the seminar will be – as far as possible – introductory.
