Title:
Stability of two-dimensional topological insulators

Speaker:
Andrea Cappelli

Abstract:
Topological insulators possess non-chiral edge excitations that can interact and decay. The criteria of stability in presence of time-reversal symmetry are reviewed and put in relation with the existence of discrete anomalies. A general analysis is presented that employs conformal field theory and partition functions.
