Inner horizon instability via the trace anomaly effective action
Julio Arrechea, Giulio Neri, Stefano Liberati
In quantum field theory applied to black hole spacetimes, substantial evidence suggests that the Unruh and Hartle-Hawking vacuum states become singular at Cauchy horizons. This rai…
Whispers from the quantum core: the ringdown of semiclassical stars
Julio Arrechea, Stefano Liberati, Vania Vellucci
This investigation delves into the ringdown signals produced by semiclassical stars, which are ultra-compact, regular solutions of the Einstein equations incorporating stress-energ…
Covariant phase space analysis of Lanczos-Lovelock gravity with boundaries
Giulio Neri, Stefano Liberati
This work introduces a novel prescription for the expression of the thermodynamic potentials associated with the couplings of a Lanczos-Lovelock theory. These potentials emerge in…
Geodesically complete universes
Raúl Carballo-Rubio, Stefano Liberati, Vania Vellucci
Singularity theorems demonstrate the inevitable breakdown of the concept of continuous, classical spacetime under highly general conditions. Quantum gravity is expected to interven…
