Sperner state and multipartite entanglement signals
Xin-Xiang Ju, Ya-Wen Sun, Yang Zhao
We establish a systematic classification scheme for multipartite entanglement structures. We define Sperner states -- a broad class of states where apparent multipartite entangleme…
Entanglement wedge cross section triangle information and holographic entanglement of assistance
Xin-Xiang Ju, Wen-Bin Pan, Ya-Wen Sun +1
We identify a non-negative and upper-bounded entanglement signal in holography which is defined as a combination of entanglement wedge cross sections (EWCS) for a tripartite mixed…
Holographic multipartite entanglement structures in IR modified geometries
Xin-Xiang Ju, Bo-Hao Liu, Ya-Wen Sun +2
We investigate how IR modifications of the bulk geometry reshape long-range multipartite entanglement on the boundary in holography. We modify the IR geometries in two opposite dir…
Upper bound of holographic entanglement entropy combinations
Xin-Xiang Ju, Ya-Wen Sun, Yang Zhao
In this work, we develop a systematic formalism to evaluate the upper bound of a large family of holographic entanglement entropy combinations when fixing subsystems and fine-t…
Holographic geometry/real-space entanglement correspondence and metric reconstruction
Xuanting Ji, Xin-Xiang Ju, Ya-Wen Sun +2
In holography, the boundary entanglement structure is believed to be encoded in the bulk geometry. In this work, we investigate the precise correspondence between the boundary real…
Modular Hamiltonian of holographic time band states
Xin-Xiang Ju, Bo-Hao Liu, Ya-Wen Sun +1
A holographic time band is a causal incomplete boundary spacetime subregion whose causal wedge is a causal complete bulk spacetime subregion. In an AdS spacetime with a specifi…
