Quantum states of the spacetime, and formation of black holes in AdS

TL;DR

This paper proposes a non-perturbative framework for quantum gravity in AdS involving two boundary field theories, providing a new perspective on black hole formation as a unitary process within this dual description.

Contribution

It introduces a dual-field theory approach with two non-interacting copies to describe quantum states of spacetime and black hole formation in AdS.

Findings

Two copies of boundary theories describe spacetime states.

Black hole formation corresponds to unitary evolution.

Framework supports non-perturbative quantum gravity description.

Abstract

We argue that a non-perturbative description of quantum gravity should involve two (non-interacting) copies of a dual field theory on the boundary, and describe the states of the spacetimes accordingly. So, for instance, a complete description of the asymptotically Anti-de-Sitter spacetimes is given by two copies of the conformal field theory associated to the global AdS spacetime. We also argue that, in this context, gravitational collapse and formation of a black hole may be described by unitary evolution of the dual non-perturbative degrees of freedom.
