A Reverse Black Hole Information Problem
Jan de Boer, Jildou Hollander, Andrew Rolph
We study the formation, detection and coarse-graining of black holes in AdS/CFT, with an emphasis on the tension between boundary unitarity and the production of mixed state Hawkin…
Scrambling or Stalling: Angular Momentum Barriers to Chaos in Holographic CFTs
Juan Hernandez, Andrew Rolph
Scrambling is a diagnostic of quantum chaos in strongly coupled systems, and plays a central role in the holographic description of black hole dynamics. We study scrambling in high…
Curious QNEIs from QNEC: New Bounds on Null Energy in Quantum Field Theory
Jackson R. Fliss, Andrew Rolph
We derive new families of quantum null energy inequalities (QNEIs), i.e. bounds on integrated null energy, in quantum field theories in two and higher dimensions. These are univers…
Quantum Bit Threads and the Entropohedron
Matthew Headrick, Sreeman Reddy Kasireddy, Andrew Rolph
We derive several new quantum bit thread prescriptions for holographic entanglement entropy, equivalent for static states to the quantum extremal surface formula. Our new prescript…
Krylov exponents and power spectra for maximal quantum chaos: an EFT approach
Saskia Demulder, Maria Knysh, Andrew Rolph
We examine the effective field theory (EFT) of maximal chaos through the lens of Krylov complexity and the Universal Operator Growth Hypothesis. We test the relationship between tw…
Page curves and replica wormholes from random dynamics
Jan de Boer, Jildou Hollander, Andrew Rolph
We show how to capture both the non-unitary Page curve and replica wormhole-like contributions that restore unitarity in a toy quantum system with random dynamics. The motivation i…
