Description
In two-dimensional quantum field theory, it has long been established that scattering amplitudes can be determined exactly in the presence of integrability. Recently, Christian Copetti, Lucia Cordova, and Shota Komatsu proposed an S-matrix that respects non-invertible symmetries. When spacetime has a boundary, one can introduce additional scattering data known as the boundary S-matrix, in addition to the bulk S-matrix. In this talk, I will discuss the boundary S-matrix in IR gapped theories with non-invertible symmetries. This presentation is based on joint work with Satoshi Yamaguchi.
