Strongly Coupled Sectors in Inflation: Gapped Theories of Unparticles

Yikun Jiang, Guilherme L. Pimentel, Chen Yang

We consider a novel scenario for a strongly coupled spectator sector during inflation, that of a higher dimensional conformal field theory with large anomalous dimensions -- ``unpa…

Coarse-Grained Fixed-Point Tensor Networks and Holographic Reflected Entropy in 3D Gravity

Ning Bao, Jinwei Chu, Yikun Jiang +1

We use the framework of to present a microscopic CFT derivation of the correspondence between reflected entropy (RE) and entanglement we…

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…

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…

Subregion duality, wedge classification and no global symmetries in AdS/CFT

Ning Bao, Yikun Jiang, Joydeep Naskar

We study various notions of `subregion duality' in the context of AdS/CFT. We highlight the differences between the `background wedge' and the `operator reconstruction wedges,' pro…

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…

Hartle-Hawking state and its factorization in 3d gravity

Wan Zhen Chua, Yikun Jiang

We study 3d quantum gravity with two asymptotically anti-de Sitter regions, in particular, using its relation with coupled Alekseev-Shatashvili theories and Liouville theory. Expre…

Entanglement entropy and edge modes in topological string theory II: The dual gauge theory story

Yikun Jiang, Manki Kim, Gabriel Wong

This is the second in a two-part paper devoted to studying entanglement entropy and edge modes in the A model topological string theory. This theory enjoys a gauge-string (Gopakuma…

Null hypersurface quantization, electromagnetic duality and asymptotic symmetries of Maxwell theory

Arpan Bhattacharyya, Ling-Yan Hung, Yikun Jiang

In this paper we consider introducing careful regularization in the quantization of Maxwell theory in the asymptotic null infinity. This allows systematic discussions of the commut…

The Area Term of the Entanglement Entropy of a Supersymmetric Vector Model in Three Dimensions

Ling-Yan Hung, Yikun Jiang, Yixu Wang

We studied the leading area term of the entanglement entropy of supersymmetric vector model in dimensions close to the line of second order phase trans…
