Constructing and Investigating Modified Black Hole Models with Quantum Corrections

ORAL

Abstract

In my recent publication, "Quasiclassical solutions for static quantum black holes," we derive novel nonlocal effects near the horizon of a quantum-corrected black hole. In this talk, I will outline two follow-up papers nearing submission. The first reinterprets this model as a quantum superposition of classical black hole spacetimes with a gaussian distribution of varying masses, broadening the applicability of the model. The second investigates the volume inside the horizon of a related quantum-corrected black hole, with implications for information content/storage. These canonical gravity approaches to constructing and exploring black hole models with quantum corrections are moving in a promising direction towards a theory of quantum gravity, and present a fertile area for further study.
