Topological orders and factorization homology
Yinghua Ai, Liang Kong, Hao Zheng
In the study of 2d (the space dimension) topological orders, it is well-known that bulk excitations are classified by unitary modular tensor categories. But these categories only d…

Classification of 2+1D topological orders and SPT orders for bosonic and fermionic systems with on-site symmetries
Tian Lan, Liang Kong, Xiao-Gang Wen
Gapped quantum liquids (GQL) include both topologically ordered states (with long range entanglement) and symmetry protected topological (SPT) states (with short range entanglement…

Modular extensions of unitary braided fusion categories and 2+1D topological/SPT orders with symmetries
Tian Lan, Liang Kong, Xiao-Gang Wen
A finite bosonic or fermionic symmetry can be described uniquely by a symmetric fusion category . In this work, we propose that 2+1D topological/SPT orders with a fixe…
