On observers in holographic maps
Chris Akers, Gracemarie Bueller, Oliver DeWolfe +3
A straightforward gravitational path integral calculation implies that closed universes are trivial, described by a one dimensional Hilbert space. Two recent papers by Harlow-Usaty…
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…
Bulk reconstruction and non-isometry in the backwards-forwards holographic black hole map
Oliver DeWolfe, Kenneth Higginbotham
The backwards-forwards map, introduced as a generalization of the non-isometric holographic maps of the black hole interior of Akers, Engelhardt, Harlow, Penington, and Vardhan to…
