Condensation Completion and Defects in 2+1D Topological Orders
Gen Yue, Longye Wang, Tian Lan
We review the condensation completion of a modular tensor category , which yields a fusion 2-category of separable algebras, bimodules over algebras and…

On a class of fusion 2-category symmetry: condensation completion of braided fusion category
Wenjie Xi, Tian Lan, Longye Wang +2
Recently, many studies are focused on generalized global symmetry, a mixture of both invertible and non-invertible symmetries in various space-time dimensions. The complete structu…
