Note on searching for critical lattice models as entropy critical points from strange correlator
Anran Jin, Ling-Yan Hung
An entropy function is proposed in [Phys. Rev. Lett. 131, 251602] as a way to detect criticality even when the system size is small. In this note we apply this strategy in the sear…
A 2D-CFT Factory: Critical Lattice Models from Competing Anyon Condensation Processes in SymTO/SymTFT
Ling-Yan Hung, Kaixin Ji, Ce Shen +2
In this paper, we introduce a ``CFT factory'' : a novel algorithm of methodically generating 2D lattice models that would flow to 2D conformal fixed points in the infrared. These 2…
It from ETH: Multi-interval Entanglement and Replica Wormholes from Large- BCFT Ensemble
Hao Geng, Ling-Yan Hung, Yikun Jiang
We provide a derivation of the Ryu-Takayanagi (RT) formula in 3D gravity for generic boundary subregion--including RT surface phase transitions--directly from the dual two-dimensio…
Universal Structures and Emergent Geometry from Large- BCFT Ensemble
Ling-Yan Hung, Yikun Jiang, Bing-Xin Lao
In this paper, we study the ensemble average of boundary CFT (BCFT) data consistent with the bootstrap equations. We apply the results to computing ensemble average of copies of mu…
Simplex tensor network renormalization group for boundary theory of 3+1D symTFT
Kaixin Ji, Lin Chen, Li-Ping Yang +1
Following the construction in arXiv:2210.12127, we develop a symmetry-preserving renormalization group (RG) flow for 3D symmetric theories. These theories are expressed as boundary…
QG from SymQRG: AdS/CFT Correspondence as Topological Symmetry-Preserving Quantum RG Flow
Ning Bao, Ling-Yan Hung, Yikun Jiang +1
By analyzing non-perturbative RG flows that explicitly preserve given topological symmetries, we show that each of their coarse-graining steps can be expressed as a quantum path in…
Building up quantum spacetimes with BCFT Legos
Ling-Yan Hung, Yikun Jiang
Is it possible to read off the quantum gravity dual of a CFT directly from its operator algebra? In this essay, we present a step-by-step recipe synthesizing results and techniques…
Deriving the non-perturbative gravitational dual of quantum Liouville theory from BCFT operator algebra
Lin Chen, Ling-Yan Hung, Yikun Jiang +1
We demonstrate that, by utilizing the boundary conformal field theory (BCFT) operator algebra of the Liouville CFT, one can express its path-integral on any Riemann surface as a th…
Precision reconstruction of rational CFT from exact fixed point tensor network
Gong Cheng, Lin Chen, Zheng-Cheng Gu +1
The novel concept of entanglement renormalization and its corresponding tensor network renormalization technique have been highly successful in developing a controlled real space r…
Bulk Operator Reconstruction in Topological Tensor Network and Generalized Free Fields
Xiangdong Zeng, Ling-Yan Hung
In this paper, we would like to study operator reconstruction in a class of holographic tensor networks describing renormalization group flows studied in arXiv:2210.12127. We study…
