Recovering the spacetime metric from a holographic dual
Netta Engelhardt, Gary T. Horowitz
We review our recent proposal to use certain spatial cross-sections of the boundary at infinity -- light-cone cuts -- to recover the conformal metric in the bulk. We discuss some e…
Into the Bulk: A Covariant Approach
Netta Engelhardt
I propose a general, covariant way of defining when one region is "deeper in the bulk" than another. This definition is formulated outside of an event horizon (or in the absence th…
New Insights into Quantum Gravity from Gauge/gravity Duality
Netta Engelhardt, Gary T. Horowitz
Using gauge/gravity duality, we deduce several nontrivial consequences of quantum gravity from simple properties of the dual field theory. These include: (1) a version of cosmic ce…
Towards a Reconstruction of General Bulk Metrics
Netta Engelhardt, Gary T. Horowitz
We prove that the metric of a general holographic spacetime can be reconstructed (up to an overall conformal factor) from distinguished spatial slices - "light-cone cuts" - of the…
The Gravity Dual of Boundary Causality
Netta Engelhardt, Sebastian Fischetti
In gauge/gravity duality, points which are not causally related on the boundary cannot be causally related through the bulk; this is the statement of boundary causality. By the Gao…
