Hamiltonian formalism, master functions and Darboux transformations for perturbed (interiors and exteriors of) nonrotating black holes
Michele Lenzi, Guillermo A. Mena Marugán, Andrés MÃnguez-Sánchez +1
Motivated by their relevance to the interior of nonrotating black holes, classical and quantum Kantowski-Sachs cosmologies have recently attracted increasing attention. This intere…
Master variables and Darboux symmetry for axial perturbations of the exterior and interior of black hole spacetimes
Michele Lenzi, Guillermo A. Mena Marugán, Andrés MÃnguez-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…
Master functions and hybrid quantization of perturbed nonrotating black hole interiors
Michele Lenzi, Guillermo A. Mena Marugán, Andrés MÃnguez-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…
Polar perturbations in Kantowski-Sachs spacetimes and hybrid quantum cosmology
Guillermo A. Mena Marugán, Andrés MÃnguez-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…
