Holographic Entanglement Propagation Through Wormholes
Kazuki Doi, Liang Li, Ung Nguyen +1
We study how energy and quantum entanglement are transferred when two identical CFTs are entangled locally. This is probed by considering a local operator insertion in one of the C…
Non-hermitian Density Matrices from Time-like Entanglement and Wormholes
Jonathan Harper, Taishi Kawamoto, Ryota Maeda +2
We extensively explore the connections between time-like entanglement and non-hermitian density matrices in quantum many-body systems. We classify setups where we encounter non-her…
Hayden--Preskill Model via Local Quenches
Weibo Mao, Tadashi Takayanagi
We model the Hayden--Preskill (HP) information recovery protocol in 2d CFTs via local joining quenches. Euclidean path integrals with slits prepare the HP subsystems: the message $…
Flat Space Holography via AdS/BCFT
Peng-Xiang Hao, Naoki Ogawa, Tadashi Takayanagi +1
In this paper, we study a new class of AdS/BCFT setups, where the world-volumes of end-of-the-world branes (EOW branes) are given by flat spaces, to explore flat space holography f…
Entanglement Suppression Due to Black Hole Scattering
Kazuki Doi, Tadashi Takayanagi
We consider the evolution of entanglement entropy in a two-dimensional conformal field theory with a holographic dual. Specifically, we are interested in a class of excited states…
Emergent Holographic Spacetime from Quantum Information
Tadashi Takayanagi
Holographic duality describes gravitational theories in terms of quantum many-body systems. In holography, quantum information theory provides a crucial tool that directly connects…
