Summary, Etc.  

요약The extreme spacetime environments of modified black holes are an ideal context in which to study possible quantum corrections. This is critical for reconciling general relativity and quantum mechanics and creating a theory of quantum gravity. In this dissertation, I use canonical gravity methods to construct, reinterpret, and probe the properties of quantum-corrected black holes, with the goal of refining modified gravity models, in the pursuit of a theory of quantum gravity. First, I construct a quasi-classical static black hole model with an additional scalar field introduced in the Hamiltonian constraint, and I derive the form of the resulting quantum effects surrounding the horizon and asymptotically. Then, I demonstrate that this model can be similarly constructed as a superposition of classical black holes of varying mass by deriving a quantum modification to the Newtonian potential in the asymptotic limit. Finally, I calculate the effect of a related quantum correction on established volume calculations for the interior of the event horizon. Together, this work provides key insights into the possible structures and behaviors of quantum black holes, opening avenues to probe the information paradox, black hole "deaths," mass uncertainty, and other mysteries of black hole physics. These advances lay the groundwork for potential future predictions such as quantum switch behaviors around quantum black holes and gravitational wave quasinormal mode observables from mergers of modified black holes.
