Abstract:

Topological insulators are intriguing materials that block conduction in their interior (the bulk) but support robust asymmetric currents along their edges. Their mathematical facets mix topology, index theory, PDEs and geometry. I will discuss these aspects then focus on a semiclassical-like regime -- in particular, proving the bulk-edge correspondence via Getzler rescaling.
