Holography from the Wheeler-DeWitt equation

arXiv:2107.14802 (2021)

In a theory of quantum gravity, states can be represented as wavefunctionals that assign an amplitude to a given configuration of matter fields and the metric on a spatial slice. These wavefunctionals must obey a set of constraints as a consequence of the diffeomor- phism invariance of the theory, the most important of which is known as the Wheeler-DeWitt equation. We study these constraints perturbatively by expanding them to leading nontrivial order in Newton’s constant about a background AdS spacetime. We show that, even within perturbation theory, any wavefunctional that solves these constraints must have specific cor- relations between a… Read More
