String Condensations in 3+1D and Lagrangian Algebras
Jiaheng Zhao, Jia-Qi Lou, Zhi-Hao Zhang +3
We present three Lagrangian algebras in the modular 2-category associated to the 3+1D topological order and discuss their physical interpretations, connecting algebr…

An invitation to topological orders and category theory
Liang Kong, Zhi-Hao Zhang
Although it has been a well-known fact, for more than two decades, that category theory is needed for the study of topological orders, it is still a non-trivial challenge for stude…

Categorical descriptions of one-dimensional gapped phases with Abelian onsite symmetries
Rongge Xu, Zhi-Hao Zhang
In this work, we analyze the macroscopic observables in the 1+1D gapped phases with Abelian onsite symmetries and show that the spacetime observables for each gapped phase form a c…
