Explore a detailed physics talk where Soichiro Shimamori from Osaka University discusses boundary scattering and non-invertible symmetries in 1+1 dimensional quantum field theories. The presentation extends recent work by Copetti, Córdova and Komatsu on how non-invertible symmetry breaking modifies conventional S-matrix crossing relations through topological quantum field theory (TQFT) effects. Learn how these modifications apply to boundary conditions, particularly how the boundary crossing relation changes when boundaries are weakly-symmetric under non-invertible symmetries. The talk analyzes kink scattering in gapped theories derived from Φ(1,3)-deformation of minimal models, demonstrating the construction of boundary S-matrices that satisfy non-invertible symmetry Ward-Takahashi identities. This collaborative research with Satoshi Yamaguchi provides advanced insights into theoretical high energy physics concepts.
