A new product entropy
Jiaju Zhang, Zhuo-Yu Xian, René Meyer +2
We propose a new product entropy, defined as the Rényi (or von Neumann) entropy of a normalized product operator constructed from two density matrices. We establish a duality showi…
Holographic Learning from Fermionic Spectra: Application to Strange Metal Phenomenology
Hong-Zhi Xiao, Zhan-Zhi He, Zhuo-Yu Xian +1
We develop a data-driven framework based on Neural ODEs that learns the effective bulk metric functions and the charge-weighted gauge potential of a static, planar-symmetric…
Boundary mutual information in double holography
Yuxuan Liu, Yi Ling, Zhuo-Yu Xian
We consider a composite system where AdS gravity is coupled to a flat heat bath and investigate the mutual information between two subregions on the intersection of the AdS…
Symmetry-Resolved Entanglement Entropy from Heat Kernels
Yuan-Chun Jing, Chao Niu, Zhuo-Yu Xian
We develop a systematic framework for computing symmetry-resolved entanglement entropies (SREE) in charged quantum systems based on an improved heat kernel approach. Although the c…
Learning geometries beyond asymptotic AdS
Cheng Ran, Shao-Feng Wu, Zhuo-Yu Xian
We present a data-driven method for holographic bulk reconstruction that works even when the spacetime is not asymptotically AdS. Given the data of boundary Green functions within…
Entropy Measures for Transition Matrices in Random Systems
Zhaohui Chen, Rene Meyer, Zhuo-Yu Xian
A transition matrix can be constructed through the partial contraction of two given quantum states. We analyze and compare four different definitions of entropy for transition matr…
