Scrambling and the black hole atmosphere
Ted Jacobson, Phuc Nguyen
We argue that the scrambling time is the same, up to a numerical factor in three or more spacetime dimensions, as the time for the atmosphere to fall across the horizon or escape,…
Light-ray moments as endpoint contributions to modular Hamiltonians
Daniel Kabat, Gilad Lifschytz, Phuc Nguyen +1
We consider excited states in a CFT, obtained by applying a weak unitary perturbation to the vacuum. The perturbation is generated by the integral of a local operator of…
Endpoint contributions to excited-state modular Hamiltonians
Daniel Kabat, Gilad Lifschytz, Phuc Nguyen +1
We compute modular Hamiltonians for excited states obtained by perturbing the vacuum with a unitary operator. We use operator methods and work to first order in the strength of the…
The Speed of Quantum Information Spreading in Chaotic Systems
Josiah Couch, Stefan Eccles, Phuc Nguyen +2
We present a general theory of quantum information propagation in chaotic quantum many-body systems. The generic expectation in such systems is that quantum information does not pr…
Diffeomorphism invariance and the black hole information paradox
Ted Jacobson, Phuc Nguyen
We argue that the resolution to the black hole information paradox lies in a proper accounting of the implications of diffeomorphism invariance for the Hilbert space and observable…
Holographic Complexity and Volume
Josiah Couch, Stefan Eccles, Ted Jacobson +1
The previously proposed "Complexity=Volume" or CV-duality is probed and developed in several directions. We show that the apparent lack of universality for large and small black ho…
