The moments of the spectral form factor in SYK

Andrea Legramandi, Neil Talwar

In chaotic quantum systems the spectral form factor exhibits a universal linear ramp and plateau structure with superimposed erratic oscillations. The mean signal and the statistic…

The Holographic Map of an Evaporating Black Hole

Zsolt Gyongyosi, Timothy J. Hollowood, S. Prem Kumar +2

We construct a holographic map that takes the semi-classical state of an evaporating black hole and its Hawking radiation to a microscopic model that reflects the scrambling dynami…

Black Hole Information Recovery in JT Gravity

Zsolt Gyongyosi, Timothy J. Hollowood, S. Prem Kumar +2

We consider the issue of information recovery for an object carrying energy and entropy into a black hole using the generalized entropy formalism, in the context of JT gravity wher…

Grey-body Factors, Irreversibility and Multiple Island Saddles

Timothy J. Hollowood, S. Prem Kumar, Andrea Legramandi +1

We consider the effect of grey-body factors on the entanglement island prescription for computing the entropy of an arbitrary subset of the Hawking radiation of an evaporating blac…

Ephemeral Islands, Plunging Quantum Extremal Surfaces and BCFT channels

Timothy J. Hollowood, S. Prem Kumar, Andrea Legramandi +1

We consider entanglement entropies of finite spatial intervals in Minkowski radiation baths coupled to the eternal black hole in JT gravity, and the related problem involving free…

Islands in the Stream of Hawking Radiation

Timothy J. Hollowood, S. Prem Kumar, Andrea Legramandi +1

We consider the island formula for the entropy of subsets of the Hawking radiation in the adiabatic limit where the evaporation is very slow. We find a simple concrete `on-shell' f…
