Classification of 2D Fermionic Systems with a Flavor Symmetry
Chi-Ming Chang, Jin Chen, Fengjun Xu
We classify superfusion categories describing two-dimensional fermionic systems equipped with the universal fermion-parity symmetry, implemented by a topological defect line (TDL)…

Fermionic Non-invertible Symmetry Behind Supersymmetric ADE Solitons
Jin Chen, Zhihao Duan, Qiang Jia +1
The non-perturbative constraints imposed by intrinsic fermionic non-invertible symmetries in 1+1 dimensional gapped systems remain largely unexplored. In this letter, we propose th…

SymTFT Approach to 2D Orbifold Groupoids: `t Hooft Anomalies, Gauging, and Partition Functions
Jin Chen, Qiang Jia
We use the 3D SymTFT approach to study the generalized symmetries and partition functions of 2D CFTs in various orbifolded and fermionic phases. These phases can be realized by the…
