Holography and Causality in the Karch-Randall Braneworld
Hao Geng, Lisa Randall
It has been argued that the existence of a geodesic shortcut in the Karch-Randall (KR) braneworld rules out the possibility for a low-energy intermediate theory, even when gravity…

Replica Wormholes and Entanglement Islands in the Karch-Randall Braneworld
Hao Geng
The Karch-Randall braneworld provides a natural set-up to study the Hawking radiation from a black hole using holographic tools. Such a black hole lives on a brane and is highly qu…

Open AdS/CFT via a Double Trace Deformation
Hao Geng
A concrete model of extracting the physics from the bulk of a gravitational universe is important to the study of quantum gravity and its possible relationship with experiments. Su…
