Hamiltonian formalism, master functions and Darboux transformations for perturbed (interiors and exteriors of) nonrotating black holes

Michele Lenzi, Guillermo A. Mena Marugán, Andrés Mínguez-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 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…

Axial perturbations in Kantowski-Sachs spacetimes and hybrid quantum cosmology

Guillermo A. Mena Marugán, Andrés Mínguez-Sánchez

Recently, there has been a growing interest in investigating homogeneous but anisotropic spacetimes owing to their relation with nonrotating, uncharged black hole interiors. We pre…
