Phase transition from eigenstate thermalization: forbidden singularity and instanton proliferation via AGT correspondence
Yongjiang Xu, Weixin Sun, Chushun Tian +1
In theoretical physics, finding connections between problems that appear in distinct contexts is an important way to leapfrog progresses, often by illuminating deep aspects that ma…
Lee-Yang paradigm of phase transition in eigenstate thermalized systems
Yongjiang Xu, Weixin Sun, Chushun Tian +1
As phase transitions in isolated quantum systems remain elusive, here we show how a thermodynamic-like phase transition, falling into the Lee-Yang paradigm, can arise in systems di…
Non-perturbative aspects of entanglement structures in -deformed CFTs
Wen-Xin Lai, Huajia Wang, Yongjiang Xu
Turning on the -deformation in a two-dimensional CFT provides a unique window to study explicitly how non-local features arise in the UV as a result of the deformation. A…
Resurgent properties of -deformed conformal field theories
Jie Gu, Yunfeng Jiang, Huajia Wang
We elaborate on the resurgence analysis on the -deformed 2d conformal field theory (CFT). Writing the deformed partition function as an infinite series in the deform…
Non-local modular flows across deformed null-cuts
Guan-Cheng Lu, Huajia Wang
Modular flows probe important aspects of the entanglement structures, especially those of QFTs, in a dynamical framework. Despite the expected non-local nature in the general cases…
Resurgence of -deformed Partition Function
Jie Gu, Yunfeng Jiang, Huajia Wang
We study non-perturbative effects of torus partition function of the -deformed 2d CFTs by resurgence. The deformed partition function can be written as an infinite series…
Subsystem entropy in 2d CFT and KdV ETH
Liangyu Chen, Anatoly Dymarsky, Jia Tian +1
We study subsystem entropy in 2d CFTs, for subsystems constituting a finite fraction of the full system. We focus on the extensive contribution, which scales linearly with the subs…
Holographic Renyi entropy of 2d CFT in KdV generalized ensemble
Liangyu Chen, Anatoly Dymarsky, Jia Tian +1
The eigenstate thermalization hypothesis (ETH) in chaotic two dimensional CFTs is subtle due to infinitely many conserved KdV charges. Previous works have demonstrated that primary…
Causal shadow and non-local modular flow: from degeneracy to perturbative genesis by correlation
Liangyu Chen, Huajia Wang
Causal shadows are bulk space-time regions between the entanglement wedges and the causal wedges, their existence encodes deep aspects of the entanglement wedge reconstruction in t…
Shape dependence of mutual information in the OPE limit: linear responses
Liangyu Chen, Huajia Wang
Mutual information serves as an important measure of correlation between subsystem components. In the framework of quantum field theories (QFTs) they have better regulated UV behav…
Enhanced corrections near holographic entanglement transitions: a chaotic case study
Xi Dong, Huajia Wang
Recent work found an enhanced correction to the entanglement entropy of a subsystem in a chaotic energy eigenstate. The enhanced correction appears near a phase transition in the e…
Barrier from chaos: operator entanglement dynamics of the reduced density matrix
Huajia Wang, Tianci Zhou
It is believed that thermalization drives the reduced density matrix of a subsystem to approach a short-range entangled operator. If the initial state is also short-range entangled…
A modular toolkit for bulk reconstruction
Thomas Faulkner, Min Li, Huajia Wang
We introduce new tools for studying modular flow in AdS/CFT. These tools allow us to efficiently extract bulk information related to causality and locality. For example, we discuss…
Probing beyond ETH at large
Thomas Faulkner, Huajia Wang
We study probe corrections to the Eigenstate Thermalization Hypothesis (ETH) in the context of 2D CFTs with large central charge and a sparse spectrum of low dimension operators. I…

Timelike BKL singularities and chaos in AdS/CFT
Edgar Shaghoulian, Huajia Wang
We study the nature of a family of curvature singularities which are precisely the timelike cousins of the spacelike singularities studied by Belinski, Khalatnikov, and Lifshitz (B…
