Exact Geometries from Boundary Gravity

TL;DR

This paper demonstrates that extremal Reissner-Nordström multi black holes can be exactly modeled in General Relativity using boundary gravity, with axions and torsion playing key roles in sourcing the geometry and highlighting dark energy's influence.

Contribution

It introduces a novel exact solution for multi black holes in an emergent gravity scenario incorporating axions and torsion.

Findings

Axion and geometric torsion source the Einstein tensor in the model.

Dark energy significantly influences the curved spacetime.

The solution provides an exact model for extremal Reissner-Nordström black holes.

Abstract

We show that the extremal Reissner-Nordstr\"{o}m type multi black holes in an emergent scenario are exact in General Relativity. It is shown that an axion in the bulk together with a geometric torsion ensure the required energy-momentum to source the $(3$$+$$1)$ geometry in the Einstein tensor. Analysis reveals a significant role of dark energy to the curved space-time.
