Description
The classical instability of the Reissner-Nordström black hole's inner Cauchy horizon leads to mass inflation. To address this, we construct a canonical quantization of the black hole interior using the Wheeler-DeWitt equation within the Einstein-Maxwell framework. We find that horizon boundary conditions dictate distinct quantum evolution scenarios: monotonic decay, quantum bounce, or "annihilation-to-nothing". Crucially, imposing an "annihilation-to-nothing" condition shifts the Cauchy horizon to the causal past of the quantum bounce, operationally removing its physical structure and suppressing mass inflation. Furthermore, the charge-neutral limit yields a strictly bounded, monotonically decaying state for the Schwarzschild black hole. These findings suggest that such quantum behaviors are generic, offering a robust pathway to resolve inner horizon instabilities.
