Abstract: | An iterative method for recovering the bulk information in asymptotically AdS spacetimes is presented. We consider zero energy
spacelike geodesics and their relation to the entanglement entropy in three dimensions to determine the metric in certain
symmetric cases. A number of comparisons are made with an alternative extraction method presented in arXiv:hep-th/0609202,
and the two methods are then combined to allow metric recovery in the most general type of static, spherically symmetric setups.
We conclude by extracting the mass and density profiles for a toy model example of a gas of radiation in (2 + 1)-dimensional
AdS. |
