Entanglement negativity and minimal entanglement wedge cross sections in holographic theories

J Kudler-Flam, S Ryu - Physical Review D, 2019 - APS
We calculate logarithmic negativity, a quantum entanglement measure for mixed quantum
states, in quantum error-correcting codes and find it to equal the minimal cross sectional …

Entanglement wedge cross section from the dual density matrix

K Tamaoka - Physical review letters, 2019 - APS
We define a new information theoretic quantity called odd entanglement entropy (OEE)
which enables us to compute the entanglement wedge cross section in holographic …

New holographic generalization of entanglement entropy

Y Nakata, T Takayanagi, Y Taki, K Tamaoka, Z Wei - Physical Review D, 2021 - APS
We introduce a new quantity, called pseudo-entropy, as a generalization of entanglement
entropy via postselection. We expect this quantity to provide a new class of order parameters …

Holographic entanglement of purification from conformal field theories

P Caputa, M Miyaji, T Takayanagi, K Umemoto - Physical Review Letters, 2019 - APS
We explore a conformal field theoretic interpretation of the holographic entanglement of
purification, which is defined as the minimal area of the entanglement wedge cross section …

Conditional and multipartite entanglements of purification and holography

N Bao, IF Halpern - Physical Review D, 2019 - APS
In this work we generalize the entanglement of purification and its conjectured holographic

[HTML][HTML] Dynamics of entanglement wedge cross section from conformal field theories

Y Kusuki, K Tamaoka - Physics Letters B, 2021 - Elsevier
We derive dynamics of the entanglement wedge cross section directly from the two-
dimensional holographic CFTs with a local operator quench. This derivation is based on the …

Quantum and classical correlations inside the entanglement wedge

K Umemoto - Physical Review D, 2019 - APS
We show that the entanglement wedge cross section (EWCS) can become larger than the
quantum entanglement measures such as the entanglement of formation in the AdS/CFT …

Holographic study of reflected entropy in anisotropic theories

MJ Vasli, MR Mohammadi Mozaffar, K Babaei Velni… - Physical Review D, 2023 - APS
We evaluate reflected entropy in certain anisotropic boundary theories dual to nonrelativistic
geometries using holography. It is proposed that this quantity is proportional to the minimal …

Mixed state entanglement measures as probe for confinement

P Jain, S Mahapatra - Physical Review D, 2020 - APS
We study holographic aspects of mixed state entanglement measures in various large N top-
down as well as bottom-up confining models. For the top-down models, we consider …
