Title |
Purifying radiation from regular black holes | |||||
| Coauthors | ||||||||
|
Abstract |
In recent year a new scenario of unitary black hole evaporation has emerged: besides resolving the curvature singularity, quantum gravity effects make the horizon metastable. In this scenario the black hole traps information for a long but finite time, therefore evading the puzzle of information loss. In this talk I discuss properties and bounds on purifying radiation emitted by a regular black hole. In particular I discuss a new relation between the energy flux and the entanglement entropy of the radiation emitted. |

Title |
The area-law sector of loop quantum gravity | |||||
| Coauthors | ||||||||
|
Abstract |
In this talk I present a concrete realization of the conjecture that semiclassical states in quantum gravity satisfy an area law. In loop quantum gravity the entanglement entropy of a random spin-network state scales linearly with the volume of a region of space. I describe a class of spin-network states that are fully characterized by the expectation value and the 2-point correlation function of geometric observables. Such states are semiclassical, have non-vanishing graviton-graviton correlations, and satisfy the area law. The framework extends previous results about the black hole horizon entropy to all regions of space. |
