Systematic Extraction of Exact Yang-Mills Solutions via Algebraic Tensor Ring Decomposition

Yu-Xuan Zhang, Jing-Ling Chen

The non-linear nature of Yang-Mills theory presents a challenge for extracting exact classical solutions, which are useful for understanding non-perturbative vacuum structures. In…

Relative Rényi Entropy Under Local Quenches in 2D CFTs

Zi-Xuan Zhao, Song He, Hao Ouyang +2

We study the relative Rényi entropy (RRE) under local quenches in two-dimensional conformal field theories (CFTs), focusing on rational CFTs (RCFTs) and holographic CFTs. In RCFTs,…

Relation between time- and spacelike entanglement entropy

Wu-zhong Guo, Song He, Yu-Xuan Zhang

In this study, we establish a connection between timelike and spacelike entanglement entropy. We show that timelike entanglement entropy is closely related to spacelike entanglemen…

Entanglement and Pseudo Entanglement Dynamics versus Fusion in CFT

Song He, Yu-Xuan Zhang, Long Zhao +1

The fusion rules and operator product expansion (OPE) serve as crucial tools in the study of operator algebras within conformal field theory (CFT). Building upon the vision of usin…

Pseudo entropy of primary operators in /-deformed CFTs

Song He, Jie Yang, Yu-Xuan Zhang +1

In this work, we investigate the time evolution of the pseudo-(Rényi) entropy after local primary operator quenches in 2D CFTs with -deformation. Using perturbatio…

Pseudo-entropy for descendant operators in two-dimensional conformal field theories

Song He, Jie Yang, Yu-Xuan Zhang +1

We study the late-time behaviors of pseudo-(Rényi) entropy of locally excited states in rational conformal field theories (RCFTs). To construct the transition matrix, we utilize tw…

Constructible reality condition of pseudo entropy via pseudo-Hermiticity

Wu-zhong Guo, Song He, Yu-Xuan Zhang

As a generalization of entanglement entropy, pseudo entropy is not always real. The real-valued pseudo entropy has promising applications in holography and quantum phase transition…

On the real-time evolution of pseudo-entropy in 2d CFTs

Wu-zhong Guo, Song He, Yu-Xuan Zhang

In this work, we study the real-time evolution of pseudo-(Rényi) entropy, a generalization of entanglement entropy, in two-dimensional conformal field theories (CFTs). We focus on…

The universality of islands outside the horizon

Song He, Yuan Sun, Long Zhao +1

We systematically calculate the quantum extremal surface (QES) associated with Hawking radiation for general -dimensional () asymptotically flat (or AdS) eternal black h…

-flow effects on torus partition functions

Song He, Yuan Sun, Yu-Xuan Zhang

In this paper, we investigate the partition functions of conformal field theories (CFTs) with the deformation on a torus in terms of the perturbative QFT approach. In La…

Revisit on holographic complexity in two-dimensional gravity

Rong-Gen Cai, Song He, Shao-Jiang Wang +1

We revisit the late-time growth rate of various holographic complexity conjectures for neutral and charged AdS black holes with single or multiple horizons in two dimensional (2D)…
