Résumé |
We show that crossing symmetry of S-matrices is modified in certain theories with non-invertible symmetries
or anomalies. Focusing on integrable flows to gapped phases in two dimensions, we find that S-matrices
derived previously from the bootstrap approach are incompatible with non-invertible symmetries along the
flow. We present consistent alternatives, which however violate standard crossing symmetry and obey
modified rules dictated by fusion categories. Based on 2403.04835 with Christian Copetti and Shota
Komatsu. |
