On anomalies and fermionic unitary operators
Masaki Okada, Shutaro Shimamura, Yuji Tachikawa +1
We point out that fermionic unitary operators which anticommute among themselves appear in various situations in quantum field theories with anomalies in the Hamiltonian formalism.…

Non-invertible symmetries act locally by quantum operations
Masaki Okada, Yuji Tachikawa
Non-invertible symmetries of quantum field theories and many-body systems generalize the concept of symmetries by allowing non-invertible operations in addition to more ordinary in…
