Quantum Universe VIDEO ColloquiumQuantum Universe VIDEO Colloquium: The entropy of Hawking radiation
Juan Maldacena (IAS Princeton)
We will review developments over the past decade on a new formula for computing gravitational entropy. This formula gives the fine grained, or von Neumann, entropy of the black hole in terms of the area of a certain minimal surface. Using this it is possible to compute the entropy of the radiation that comes out of a black hole. With this new formula one obtains a result that follows the results expected for a unitary theory, as opposed to the result obtained by Hawking.
