Title	Probing Gravity using Correlation Measures
Abstract	Recent progress in understanding connection between gravity and quantum information enabled us to understand some non perturbative effects in quantum gravity, so called island formula which resolved a version of Hawking’s black hole information paradox. In this talk I will extend this computation in two directions. First I will consider bi-partite correlation measures in Hawking radiation and study its entanglement structure, by proposing island formula for reflected entropy. Second, I will extend the formula to entanglement entropy of matter field in general spacetime. We found an island in imaginary time direction, and the entanglement entropy of the matter cannot exceed the area of the island.
