Condensed Matter Theory Seminar - Shinsei Ryu (University of Illinois-Urbana Champaign), "Fermionic symmetry protected topological phases with reflection symmetry and global anomalies"
Quantum anomalies, breakdown of classical symmetries by quantum effects, provide a sharpdefinition of symmetry protected topological (SPT) phases. In particular, they can diagnose interactioneffects on the non-interacting classification of fermionic SPT phases. In this talk, I will discussvarious examples of topological superconductors with reflection symmetries in (2+1) and (3+1) dimensions.In particular, I will focus on how interaction effects can modify free-fermion classifications byidentifying global quantum anomalies at the boundary of these systems.
