A group theoretic calculation of multi-invariants of some stabilizer states
Bartlomiej Czech, Yichen Feng, Jonathan Harper +1
We study multi-invariants---a multi-partite generalization of Renyi entropies---of simple stabilizer states, for an arbitrary replica symmetry group. We develop a group theoretic t…
Rényi Multi-entropy for Stabilizer States: A Finite Field Gauss Sum Problem
Bartlomiej Czech, Yichen Feng, Jonathan Harper +2
Rényi multi-entropy probes multi-partite structure beyond bipartite spectra, but its behavior in general quantum states and the entanglement structure it captures remain poorly und…
Holographic multipartite entanglement dynamics in AdS-Vaidya
Xin-Xiang Ju, Ya-Wen Sun, Yang Zhao +1
We study how multipartite entanglement is dynamically reorganized during holographic thermalization following a global quench in AdS/CFT. We first use the -partite infor…
Long-range multipartite entanglement in holographic gapless systems
Xiantong Chen, Xuanting Ji, Xin-Xiang Ju +2
Gapless quantum systems support correlations over arbitrarily long distances, giving rise to power-law long-range entanglement. We investigate long-range entanglement at strong cou…
The Holographic Multi-Entropy Cone
Xin-Xiang Ju, Yang Zhao
We generalize the holographic entropy cone (HEC) to the holographic multi-entropy cone (HMEC) by adjoining multi-entropy coordinates to the standard bipartition entropy coordinates…
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…
Holographic multipartite entanglement from the upper bound of -partite information
Xin-Xiang Ju, Wen-Bin Pan, Ya-Wen Sun +1
To analyze the holographic multipartite entanglement structure, we study the upper bound for holographic -partite information that fixed boundary subregions p…
More on the upper bound of holographic n-partite information
Xin-Xiang Ju, Wen-Bin Pan, Ya-Wen Sun +2
We show that there exists a huge amount of multipartite entanglement in holography by studying the upper bound for holographic -partite information that fixed bounda…
Entanglement structures from modified IR geometry
Xin-Xiang Ju, Teng-Zhou Lai, Bo-Hao Liu +2
We investigate a new proposal connecting the geometry at various radial scales in asymptotic AdS spacetime with entanglement structure at corresponding real-space length scales of…
Squashed Entanglement from Generalized Rindler Wedge
Xin-Xiang Ju, Bo-Hao Liu, Wen-Bin Pan +2
We investigate the bipartite and multipartite quantum entanglement structure in gravity and the dual holographic field theory based on the generalized Rindler wedge formalism. We d…
Holographic n-partite Information in Hyperscaling Violating Geometry
Xin-Xiang Ju, Teng-Zhou Lai, Ya-Wen Sun +1
The -partite information (nI) is formulated as a measure of multi-partite entanglement. Field theory computation revealed that the sign of nI is indefinite for , while…
Generalized Rindler Wedge and Holographic Observer Concordance
Xin-Xiang Ju, Wen-Bin Pan, Ya-Wen Sun +1
Defining gravitational subsystems has long been challenging due to the lack of the conventional notion of locality in gravity. In this work, we define gravitational subsystems from…
