On lattice models of gapped phases with fusion category symmetries
Kansei Inamura
We construct topological quantum field theories (TQFTs) and commuting projector Hamiltonians for any 1+1d gapped phases with non-anomalous fusion category symmetries, i.e. finite s…

Topological field theories and symmetry protected topological phases with fusion category symmetries
Kansei Inamura
Fusion category symmetries are finite symmetries in 1+1 dimensions described by unitary fusion categories. We classify 1+1d time-reversal invariant bosonic symmetry protected topol…
