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…
Christ-Lee Model: (Anti-)Chiral Supervariable Approach to BRST Formalism
B. Chauhan, S. Kumar
We derive the off-shell nilpotent of order two and absolutely anti-commuting Becchi-Rouet-Stora-Tyutin (BRST), anti-BRST and (anti-)co-BRST symmetry transformations for the Christ-…
