Quantum dust cores of rotating black holes

TL;DR

This paper develops a quantum model for dust cores in rotating black holes by quantizing dust particle geodesics, revealing how angular momentum influences core size and interior geometry.

Contribution

It generalizes previous spherical models to include rotation, incorporating angular momentum effects into the quantum description of black hole cores.

Findings

Angular momentum affects the size of the black hole core.

The interior geometry is modified by rotation.

Quantum dust cores can be modeled beyond spherical symmetry.

Abstract

Black holes are spacetimes that should describe the end state of the gravitational collapse of huge amounts of quantum matter. A quantum description of dust cores for black hole geometries that accounts for the large number of matter constituents can be obtained by quantising the geodesic motion of dust particles and finding the corresponding many-body ground state. We here generalise previous works in spherical symmetry to rotating geometries and show the effect of angular momentum on the size of the core and effective interior geometry.
