Maximal Total Quantum Dimension at Bounded Rank in WZW Modular Tensor Categories
Ce Shen
We determine the maximal torus topological entanglement entropy (TEE) at bounded torus ground-state degeneracy within simply connected untwisted Wess--Zumino--Witten theories. For…
CFT from TQFT via Holographic Tensor Network, and Precision Discretisation of CFT
Lin Chen, Haochen Zhang, Kaixin Ji +4
We show that the path-integral of conformal field theories in dimensions (CFT) can be constructed by solving for eigenstates of an RG operator following from the Turaev-Vir…
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…
A Defect Verlinde Formula
Ce Shen, Ling-Yan Hung
We revisit the problem of boundary excitations at a topological boundary or junction defects between topological boundaries in non-chiral bosonic topological orders in 2+1 dimensio…
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…
