Boundary Scattering and Non-invertible Symmetries in 1+1 Dimensions
Soichiro Shimamori, Satoshi Yamaguchi
Recent studies by Copetti, Córdova and Komatsu have revealed that when non-invertible symmetries are spontaneously broken, the conventional crossing relation of the S-matrix is mo…

Exotic massive fermionic systems with huge vacuum degeneracy at boundaries
Hiroki Kawakami, Satoshi Yamaguchi
We investigate a massive non-relativistic fermionic system exhibiting exotic features. When the mass parameter is set to zero, the system acquires the fermionic subsystem symmetry.…
