SHEP Friday Seminar - Neil Talwar - Information recovery from evaporating black holes in JT gravity - Event

46/5081 and on Teams

Event details

​Recent developments on the black hole information problem have shown how the quantum extremal surface (QES) prescription may be used to obtain a Page curve and reproduce the Hayden-Preskill decoding criterion. In this talk, I will use the QES prescription to study when the information content of an object which falls into a black hole may be recovered in the radiation, in a model of JT gravity. I will show how the backreaction on the geometry created by the infalling object can be solved exactly in this model and how this allows us to reproduce the decoding criterion but with some refinements.
