Master functions and hybrid quantization of perturbed nonrotating black hole interiors
Michele Lenzi, Guillermo A. Mena Marugán, Andrés Mínguez-Sánchez
Master functions of black holes are fundamental tools in gravitational-wave physics and are typically derived within a Lagrangian framework. Starting from the Kantowski-Sachs geome…
Master variables and Darboux symmetry for axial perturbations of the exterior and interior of black hole spacetimes
Michele Lenzi, Guillermo A. Mena Marugán, Andrés Mínguez-Sánchez +1
Recent efforts have shown that Kantowski-Sachs spacetime provides a useful framework for analyzing perturbations inside a Schwarzschild black hole (BH). In these studies, the adopt…
Polar perturbations in Kantowski-Sachs spacetimes and hybrid quantum cosmology
Guillermo A. Mena Marugán, Andrés Mínguez-Sánchez
Increasing attention has been recently devoted to the study of Kantowski-Sachs spacetime as a way to explore the interior of a Schwarzschild black hole. In this work, we construct…
