Pseudoentropy in and Timelike Entanglement Entropy

K Doi, J Harper, A Mollabashi, T Takayanagi, Y Taki - Physical Review Letters, 2023‏ - APS
We study holographic entanglement entropy in dS/CFT and introduce timelike entanglement
entropy in CFTs. Both of them take complex values in general and are related with each …

Timelike entanglement entropy

J Harper, A Mollabashi, T Takayanagi, Y Taki - Journal of High Energy …, 2023‏ - Springer
A bstract We define a new complex-valued measure of information called the timelike
entanglement entropy (EE) which in the boundary theory can be viewed as a Wick rotation …

Entangled universes in dS wedge holography

SE Aguilar-Gutierrez, AK Patra, JF Pedraza - Journal of High Energy …, 2023‏ - Springer
A bstract We develop a new setting in the framework of braneworld holography to describe a
pair of coupled and entangled uniformly accelerated universes. The model consists of two …

From time-reversal symmetry to quantum Bayes' rules

AJ Parzygnat, J Fullwood - PRX Quantum, 2023‏ - APS
Bayes' rule, P (B| A) P (A)= P (A| B) P (B), is one of the simplest yet most profound,
ubiquitous, and far-reaching results of classical probability theory, with applications in any …

Rényi entanglement asymmetry in ()-dimensional conformal field theories

M Chen, HH Chen - Physical Review D, 2024‏ - APS
In this paper, we consider the Rényi entanglement asymmetry of excited states in the (1+ 1)
dimensional free compact boson conformal field theory (CFT) at equilibrium. We obtain a …

A universal approach to Krylov state and operator complexities

M Alishahiha, S Banerjee - SciPost Physics, 2023‏ - scipost.org
We present a general framework in which both Krylov state and operator complexities can
be put on the same footing. In our formalism, the Krylov complexity is defined in terms of the …

A half de Sitter holography

T Kawamoto, SM Ruan, Y Suzuki… - Journal of High Energy …, 2023‏ - Springer
A bstract A long-standing and intriguing question is: does the holographic principle apply to
cosmologies like de Sitter spacetime? In this work, we consider a half dS spacetime wherein …

AdS/BCFT with brane-localized scalar field

H Kanda, M Sato, Y Suzuki, T Takayanagi… - Journal of High Energy …, 2023‏ - Springer
A bstract In this paper, we study the dynamics of end-of-the-world (EOW) branes in AdS with
scalar fields localized on the branes as a new class of gravity duals of CFTs on manifolds …

Further remarks on de Sitter space, extremal surfaces, and time entanglement

K Narayan - Physical Review D, 2024‏ - APS
We develop further the investigations by Narayan [de Sitter space, extremal surfaces, and
time entanglement, Phys. Rev. D 107, 126004 (2023) PRVDAQ 2470-0010 …

Timelike entanglement entropy in dS3/CFT2

X Jiang, P Wang, H Wu, H Yang - Journal of High Energy Physics, 2023‏ - Springer
A bstract In the context of dS 3/CFT 2, we propose a timelike entanglement entropy defined
by the renormalization group flow. This timelike entanglement entropy is calculated in CFT …
