Subregion observer rules from generalized entanglement wedges
Lana Bozanic, Kenneth Higginbotham, Chris Waddell
We consider rules for modifying holographic tensor networks proposed in two independent contexts: by the Colorado (CO) group in 2503.09681 to incorporate observers in holographic m…
Helping observers in closed universes reach their full potential
Kenneth Higginbotham
Recent work by Engelhardt, Gesteau, and Harlow applies proposals for incorporating observers into holographic maps to study the Antonini-Rath puzzle for closed universes. In a new…
On tests for baby universes in AdS/CFT
Kenneth Higginbotham
To address a puzzle by Antonini and Rath -- where a single CFT state has two bulk duals, one with a baby universe and one without -- Engelhardt and Gesteau recently devised a test…
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…
Non-isometric codes for the black hole interior from fundamental and effective dynamics
Oliver DeWolfe, Kenneth Higginbotham
We introduce a new holographic map for encoding black hole interiors by including both fundamental and effective dynamics. This holographic map is constructed by evolving a state i…
Entanglement entropy and non-local duality: quantum channels and quantum algebras
Oliver DeWolfe, Kenneth Higginbotham
We investigate the transformation of entanglement entropy under dualities, using the Kramers-Wannier duality present in the transverse field Ising model as our example. Entanglemen…
Generalized symmetries and 2-groups via electromagnetic duality in AdS/CFT
Oliver DeWolfe, Kenneth Higginbotham
We discuss how electromagnetically dualizing a 1-form to a 2-form in AdS exchanges regular and alternate boundary conditions, and thus gauges the originally global symme…
Coping with Junk Radiation in Binary Black Hole Simulations
Kenny Higginbotham, Bhavesh Khamesra, Jame P. McInerney +3
Spurious junk radiation in the initial data for binary black hole numerical simulations has been an issue of concern. The radiation affects the masses and spins of the black holes,…
Microcanonical analysis of Boltzmann and Gibbs Entropies in trapped cold atomic gases
Kenneth J. Higginbotham, Daniel E. Sheehy
We analyze a gas of noninteracting fermions confined to a one-dimensional harmonic oscillator potential, with the aim of distinguishing between two proposed definitions of the ther…
