CMSA Quantum Matter in Mathematics and Physics: Global Anomalies on the Hilbert Space

CMSA EVENTS

Speaker:

Jaume Gomis - Perimeter PI

We will discuss an elementary way of detecting some global anomalies from the way the symmetry algebra is realized on the torus Hilbert space of the anomalous theory, give a physical description of the imprint of the “layers” that enter in the cobordism classification of anomalies and discuss applications, including how anomalies can imply a supersymmetric spectrum in strongly coupled (nonsupersymmetric) gauge theories.
