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…
A (Dummy's) Guide to Working with Gapped Boundaries via (Fermion) Condensation
Jiaqi Lou, Ce Shen, Chaoyi Chen +1
We study gapped boundaries characterized by "fermionic condensates" in 2+1 d topological order. Mathematically, each of these condensates can be described by a super commutative Fr…
Ishibashi States, Topological Orders with Boundaries and Topological Entanglement Entropy II -- Cutting through the boundary
Ce Shen, Jiaqi Lou, Ling-Yan Hung
We compute the entanglement entropy in a 2+1 dimensional topological order in the presence of gapped boundaries. Specifically, we consider entanglement cuts that cut through the bo…
Ishibashi States, Topological Orders with Boundaries and Topological Entanglement Entropy
Jiaqi Lou, Ce Shen, Ling-Yan Hung
In this paper, we study gapped edges/interfaces in a 2+1 dimensional bosonic topological order and investigate how the topological entanglement entropy is sensitive to them. We pre…
