Gauging non-invertible symmetries on the lattice
Sahand Seifnashri, Shu-Heng Shao, Xinping Yang
We provide a general prescription for gauging finite non-invertible symmetries in 1+1d lattice Hamiltonian systems. Our primary example is the Rep(D) fusion category generated…
Non-invertible SPTs: an on-site realization of (1+1)d anomaly-free fusion category symmetry
Chenqi Meng, Xinping Yang, Tian Lan +1
We investigate (1+1)d symmetry-protected topological (SPT) phases with fusion category symmetries. We emphasize that the UV description of an anomaly-free fusion category symmetry…
Boundary topological orders of (4+1)d fermionic SPT states
Meng Cheng, Juven Wang, Xinping Yang
We investigate (3+1)d topological orders in fermionic systems with an anomalous symmetry, where its subgroup is the fermi…
Gapped boundary of (4+1)d beyond-cohomology bosonic SPT phase
Xinping Yang, Meng Cheng
In this work we study gapped boundary states of bosonic symmetry-protected topological (SPT) phases in 4+1d, which are characterized by mixed -gravity…
