Island paradigm and information recovery from radiation
Abstract The island paradigm for an AdS2 eternal black hole in the Hartle-Hawking state coupled to a finite temperature non-gravitating bath asserts that after the Page time the operators in the black hole interior can be reconstructed using the bath degrees of freedom. We demonstrate this assertion...

| description | Abstract The island paradigm for an AdS2 eternal black hole in the Hartle-Hawking state coupled to a finite temperature non-gravitating bath asserts that after the Page time the operators in the black hole interior can be reconstructed using the bath degrees of freedom. We demonstrate this assertion by consideing a special operator U bath $$ {\mathbbm{U}}_{\textrm{bath}} $$ that has nontrivial action only on the bath degrees of freedom. We show via the gravitational Euclidean path integral analysis that though before the Page time U bath $$ {\mathbbm{U}}_{\textrm{bath}} $$ does not translate the operators in the bath to the black hole interior, after the Page time it takes them to the black hole interior. |
