Negative energy enhancement in layered holographic conformal field theories
Alex May, Petar Simidzija, Mark Van Raamsdonk
Using a holographic model, we study quantum field theories with a layer of one CFT surrounded by another CFT, on either a periodic or an infinite direction. We study the vacuum ene…

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…

Positive gravitational subsystem energies from CFT cone relative entropies
Dominik Neuenfeld, Krishan Saraswat, Mark Van Raamsdonk
The positivity of relative entropy for spatial subsystems in a holographic CFT implies the positivity of certain quantities in the dual gravitational theory. In this note, we consi…
