The horocycle regulator: exact cutoff-independence in AdS/CFT
Sristy Agrawal, Oliver DeWolfe, Kenneth Higginbotham +1
While the entanglement entropy of a single subregion in quantum field theory is formally infinite and requires regularization, certain combinations of entropies are perfectly finit…

Tensor networks for black hole interiors: non-isometries, quantum extremal surfaces, and wormholes
Gracemarie Bueller, Oliver DeWolfe, Kenneth Higginbotham
We use hyperbolic tensor networks to construct a holographic map for black hole interiors that adds a notion of locality to the non-isometric codes proposed by Akers, Engelhardt, H…
