Pointed Drinfeld center functor
Liang Kong, Wei Yuan, Hao Zheng
In this work, using the functoriality of Drinfeld center of fusion categories, we generalize an earlier result on the functoriality of full center of simple separable algebras in a…
A mathematical theory of gapless edges of 2d topological orders. Part II
Liang Kong, Hao Zheng
This is the second part of a two-part work on the unified mathematical theory of gapped and gapless edges of 2+1D topological orders. In Part I, we have developed the mathematical…
Gapped domain walls between 2+1D topologically ordered states
Tian Lan, Xueda Wen, Liang Kong +1
The 2+1D topological order can be characterized by the mapping-class-group representations for Riemann surfaces of genus-1, genus-2, etc. In this paper, we use those representation…
A mathematical theory of gapless edges of 2d topological orders. Part I
Liang Kong, Hao Zheng
This is the first part of a two-part work on a unified mathematical theory of gapped and gapless edges of 2d topological orders. We analyze all the possible observables on the 1+1D…
The center of monoidal 2-categories in 3+1D Dijkgraaf-Witten Theory
Liang Kong, Yin Tian, Shan Zhou
In this work, for a finite group and a 4-cocycle , we compute explicitly the center of the monoidal 2-category of -…
A topological phase transition on the edge of the 2d topological order
Wei-Qiang Chen, Chao-Ming Jian, Liang Kong +2
The unified mathematical theory of gapped and gapless edges of 2d topological orders was developed by two of the authors. It provides a powerful tool to study pure edge topological…
