Multi-gap topology & non-abelian braiding in k-space

Gunnar F. Lange, Cambridge

Weekly Theory Seminar.

Abstract

In recent years, topological phases in band structures have received invigorated interest as various sophisticated classification schemes have been developed.  Amongst the most intriguing recent developments in this area are multi-gap topologies, which can host non-abelian topological invariants. In this talk, I will provide an overview of these phases in both electronic and phononic systems. I will also discuss possible experimental realizations.
