Apparent horizons in cosmologically-embedded black holes
Mariano Cadoni, Mirko Pitzalis, Andrea Pierfrancesco Sanna
We present exact solutions for the cosmological embedding of a broad class of non-singular black holes, demonstrating that these objects exhibit an apparent horizon. The evolution…
Effective Quantum Spacetimes from Functional Renormalization Group
Alfio Bonanno, Mariano Cadoni, Mirko Pitzalis +1
Using the Functional Renormalization Group approach we construct effective quantum spacetime geometries by self-consistently deforming the classical Schwarzschild-de Sitter black-h…
Nucleation of de Sitter from the anti de Sitter spacetime in scalar field models
Mariano Cadoni, Mirko Pitzalis, Andrea P. Sanna
We show that, in the framework of Einstein-scalar gravity, the gravitational coupling can drive the nucleation of the de Sitter (dS) spacetime from an anti de Sitter (AdS) one. Thi…
Cosmological coupling of local gravitational systems
Mariano Cadoni, Mirko Pitzalis, Davi C. Rodrigues +1
We investigate the cosmological coupling of spherical, local astrophysical systems. We derive a general formula quantifying the cosmological coupling of the Misner-Sharp mass of th…
