Topological insulators are striking quantum materials which block electricity in their interior but support robust currents along their boundary. The bulk-edge correspondence is a physical principle that expresses the conductance of the boundary in terms of a bulk topological invariant. We will give a state-of-the-art review of the subject, including recent results in collaboration with Xiaowen Zhu.

This talk will be on Zoom.
