Monitoring a de Sitter universe through an anti-de Sitter window
Sarah Hoback, Daniel L. Jafferis, Zixia Wei
We propose that AdS gravity coupled to dS end-of-the-world branes is dual to a unitary holographic CFT with non-unitary conformal boundary conditions. These boundary co…
Pure states for subregions in gravity and their entanglement entropy
Zixia Wei
It is proposed that spatial subregions in quantum gravity can be assigned pure states, rather than mixed reduced density matrices. The state is prepared by a partially frozen gravi…
A Tale of Two Hartle-Hawking Wave Functions: Fully Gravitational vs Partially Frozen
Galit Anikeeva, Raphaël Dulac, Zixia Wei +1
We revisit the Hartle-Hawking wave function in AdS spacetime, where natural spatial slices are open and require an additional spacetime boundary. This leads to two constructions: a…
CFT derivation of entanglement phase transition in pseudo entropy
Hiroki Kanda, Tadashi Takayanagi, Zixia Wei
In this paper, we discuss the entanglement phase transition of pseudo entropy in CFTs. We focus on the case where the in-state and the out-state are different boundary states relat…
Wormholes with Ends of the World
Diandian Wang, Zhencheng Wang, Zixia Wei
We study classical wormhole solutions in 3D gravity with end-of-the-world (EOW) branes, conical defects, kinks, and punctures. These solutions compute statistical averages of an en…
Localized Black Holes in AdS: What Happens Below c/12 Stays Below c/12
Iosif Bena, Raphaël Dulac, Pierre Heidmann +1
We construct asymptotically AdSST black holes that are localized on the S and co-exist with the BTZ black hole at small positive energies. These black…
Holographic Dual of Crosscap Conformal Field Theory
Zixia Wei
We propose a holographic dual for 2D CFT defined on closed non-orientable manifolds, such as the real projective plane and the Klein bottle . Such CFT…
Entanglement Phase Transition in Holographic Pseudo Entropy
Hiroki Kanda, Taishi Kawamoto, Yu-ki Suzuki +3
In this paper, we present holographic descriptions of entanglement phase transition using AdS/BCFT. First, we analytically calculate the holographic pseudo entropy in the AdS/BCFT…
Efficient Simulation of Low Temperature Physics in One-Dimensional Gapless Systems
Yuya Kusuki, Kotaro Tamaoka, Zixia Wei +1
We discuss the computational efficiency of the finite temperature simulation with the minimally entangled typical thermal states (METTS). To argue that METTS can be efficiently rep…
Universal entanglement signatures of interface conformal field theories
Qicheng Tang, Zixia Wei, Yin Tang +2
An interface connecting two distinct conformal field theories hosts rich critical behaviors. In this work, we investigate the entanglement properties of such critical interface the…
SVD Entanglement Entropy
Arthur J. Parzygnat, Tadashi Takayanagi, Yusuke Taki +1
In this paper, we introduce a new quantity called SVD entanglement entropy. This is a generalization of entanglement entropy in that it depends on two different states, as in pre-…
AdS/BCFT with Brane-Localized Scalar Field
Hiroki Kanda, Masahide Sato, Yu-ki Suzuki +2
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 with bo…
Counting atypical black hole microstates from entanglement wedges
Zixia Wei, Yasushi Yoneta
Disentangled black hole microstates are atypical states in holographic CFTs whose gravity duals do not have smooth horizons. If there exist sufficiently many disentangled microstat…
AdS/BCFT from Conformal Bootstrap: Construction of Gravity with Branes and Particles
Yuya Kusuki, Zixia Wei
We initiate a conformal bootstrap program to study AdS3/BCFT2 with heavy excitations. We start by solving the bootstrap equations associated with two-point functions of scalar/non-…
Zoo of holographic moving mirrors
Ibrahim Akal, Taishi Kawamoto, Shan-Ming Ruan +2
We systematically study moving mirror models in two-dimensional conformal field theory (CFT). By focusing on their late-time behavior, we separate the mirror profiles into four cla…
On the Page curve under final state projection
Ibrahim Akal, Taishi Kawamoto, Shan-Ming Ruan +2
The black hole singularity plays a crucial role in formulating Hawking's information paradox. The global spacetime analysis may be reconciled with unitarity by imposing a final sta…
Causal Structures and Nonlocality in Double Holography
Hidetoshi Omiya, Zixia Wei
Double holography plays a crucial role in recent studies of Hawking radiation and information paradox by relating an intermediate picture, in which a dynamical gravity living on an…

Pseudo Entropy in Free Quantum Field Theories
Ali Mollabashi, Noburo Shiba, Tadashi Takayanagi +2
Pseudo entropy is an interesting quantity with a simple gravity dual, which generalizes entanglement entropy such that it depends on both an initial and a final state. Here we reve…
Codimension two holography for wedges
Ibrahim Akal, Yuya Kusuki, Tadashi Takayanagi +1
We propose a codimension two holography between a gravitational theory on a dimensional wedge spacetime and a dimensional CFT which lives on the corner of the wedge. Fo…
Holographic Pseudo Entropy
