CMSA Quantum Matter in Mathematics and Physics: When does a three-dimensions Chern-Simons theory have a time reversal symmetry?

In this talk, I will discuss the time reversal invariance of (spin-) Chern-Simons theory in 3 dimensions at both classical and quantum levels. I will show how to obtain a complete classification of Abelian anyons with the time reversal symmetry expressed in terms of the higher Gauss sums. Then, I will comment on the time reversal symmetry of Chern-Simons in the non-Abelian case.

This seminar will be on Zoom.
