Holographic BCFT Spectra from Brane Mergers
Shovon Biswas, Jani Kastikainen, Sanjit Shashi +1
We use holography to study the spectra of boundary conformal field theories (BCFTs). To do so, we consider a 2-dimensional Euclidean BCFT with two circular boundaries that correspo…
The Spectrum of Boundary States in Symmetric Orbifolds
Alexandre Belin, Shovon Biswas, James Sully
We give an explicit construction of the complete set of Cardy boundary states that respect the extended chiral algebra for symmetric product orbifolds. The states are labelled by a…
Looking for (and not finding) a bulk brane
Wyatt Reeves, Moshe Rozali, Petar Simidzija +3
When does a holographic CFT with a boundary added to it (a BCFT) also have a `good' holographic dual with a localized gravitating end-of-the-world brane? We argue that the answer t…
Random Matrix Theory for Complexity Growth and Black Hole Interiors
Arjun Kar, Lampros Lamprou, Moshe Rozali +1
We study a precise and computationally tractable notion of operator complexity in holographic quantum theories, including the ensemble dual of Jackiw-Teitelboim gravity and two-dim…
BCFT entanglement entropy at large central charge and the black hole interior
James Sully, Mark Van Raamsdonk, David Wakeham
In this note, we consider entanglement and Renyi entropies for spatial subsystems of a boundary conformal field theory (BCFT) or of a CFT in a state constructed using a Euclidean B…
Eigenstate Thermalization and Disorder Averaging in Gravity
Jason Pollack, Moshe Rozali, James Sully +1
Naively, a resolution of the black hole information paradox appears to involve microscopic details of a theory of quantum gravity. However, recent work has argued that a unitary Pa…
