Quantum black hole ringdown
Konstantinos Topaloglou, Elena Cuoco, Roberto Casadio
The ringdown of a black hole following a merger is a potential candidate for revealing the signatures of quantum gravity in the emerging gravitational waves. In quantum theory, bla…
Regular Schwarzschild black holes and cosmological models
Roberto Casadio, Alexander Kamenshchik, Jorge Ovalle
We study regular Schwarzschild black holes in General Relativity as an alternative to the singular counterpart. We analyze two types of solutions which are completely parameterised…
Cosmology from Schwarzschild black hole revisited
Roberto Casadio, Alexander Kamenshchik, Jorge Ovalle
We study cosmological models based on the interior of the revisited Schwarzschild black hole recently reported in [Phys.~Rev.~D{\bf 109} (2024) 104032]. We find that these solution…
Relaxation of first-class constraints and the quantization of gauge theories: from "matter without matter" to the reappearance of time in quantum gravity
Roberto Casadio, Leonardo Chataignier, Alexander Yu. Kamenshchik +3
We make a conceptual overview of a particular approach to the initial-value problem in canonical gauge theories. We stress how the first-class phase-space constraints may be relaxe…
From black hole mimickers to black holes
Roberto Casadio, Alexander Kamenshchik, Jorge Ovalle
We present a simple analytical model for studying the collapse of an ultracompact stellar object (regular black hole mimicker with infinite redshift surface) to form a (integrable)…
Slowly rotating quantum dust cores and black holes
Roberto Casadio, Luca Tabarroni
We study the effect of rotation on the spectrum of bound states for dust cores that source (quantum) black holes found in Eur. Phys. J. C 82 (2022) 10. The dust ball is assumed to…
