Self-duality under gauging a non-invertible symmetry
Yichul Choi, Da-Chuan Lu, Zhengdi Sun
We discuss two-dimensional conformal field theories (CFTs) which are invariant under gauging a non-invertible global symmetry. At every point on the orbifold branch of CFTs,…
Quantization of Axion-Gauge Couplings and Non-Invertible Higher Symmetries
Yichul Choi, Matthew Forslund, Ho Tat Lam +1
We derive model-independent quantization conditions on the axion couplings (sometimes known as the anomaly coefficients) to the Standard Model gauge group $[SU(3)\times SU(2)\times…
Remarks on Boundaries, Anomalies, and Noninvertible Symmetries
Yichul Choi, Brandon C. Rayhaun, Yaman Sanghavi +1
What does it mean for a boundary condition to be symmetric with respect to a non-invertible global symmetry? We discuss two possible definitions in 1+1d. On the one hand, we call a…
