Proof of the entropic -theorem
Jonah Kudler-Flam
We prove an entropic -theorem in two dimensions by constructing a -function from the mutual information between spacelike separated wedges, defined through the relative entro…
The cosmological necklace problem
Andreas Blommaert, Jonah Kudler-Flam, Vladimir Narovlansky +1
We investigate 3d de Sitter axion wormhole which contribute to the no-boundary density matrix. We identify "cosmological necklace" solutions: an infinite series of Euclidean saddle…
Logarithmic negativity typically equals exact entanglement cost
Bowen Ouyang, Jonah Kudler-Flam
Quantum entanglement plays a leading role in modern understanding of physical systems, from quantum phases of matter to quantum gravity. In quantum information theory, one seeks op…
Wormholes and Averaging over N
Jonah Kudler-Flam, Edward Witten
The gravitational path integral produces an asymptotic expansion in , a fact which is puzzling in the case of observables that are expected to fluctuate wildly. Wormholes appe…
Generalized Entropy is von Neumann Entropy II: The complete symmetry group and edge modes
Marc S. Klinger, Jonah Kudler-Flam, Gautam Satishchandran
We consider the algebra of observables of perturbative quantum gravity in the exterior of a stationary black hole or the static patch of de Sitter spacetime. It was previously argu…
