Black hole information recovery in JT gravity

A bstract We consider the issue of information recovery for an object carrying energy and entropy into a black hole using generalized formalism, in context JT gravity where backreaction problem can be solved exactly. verify main aspects Hayden-Preskill scenario but with some refinements. show that is encoded Hawking radiation redundant way, as expected quantum error correcting code. how extremal surfaces associated to have form python’s lunch thereby complexity decoding exponential combination shift object. also infalling observer must smooth experience at horizon we calculate their endurance proper time inside before they are radiated out.
