Thermomechanics of Horndeski Scalar Hair with Spacelike Gradients
Marcello Miranda, Marco Sebastianutti, Andrea Giusti
We develop a thermomechanical framework for viable Horndeski scalar hair with spacelike scalar-field gradients. Adapting the formalism to the scalar configuration, we…
On Modelling the Surfaces of Celestial Bodies in Quantum Gravity
Xavier Calmet, Marco Sebastianutti
We discuss how to model the surface of celestial bodies (such as stars) in quantum gravity to ensure the regularity of quantum corrections to classical solutions of general relativ…
Singularity and differentiability at the origin of static and spherically symmetric black holes
Tommaso Antonelli, Marco Sebastianutti
The divergence of curvature invariants at a given point signals the impossibility of extending the spacetime to that point, with the derivative order of these diverging invariants…
Black Hole Solutions in Quantum Gravity with Vilkovisky-DeWitt Effective Action
Xavier Calmet, Andrea Giusti, Marco Sebastianutti
We study new black hole solutions in quantum gravity. We use the Vilkovisky-DeWitt unique effective action to obtain quantum gravitational corrections to Einstein's equations. In f…
Coherent electrically-charged quantum black holes
Tommaso Antonelli, Marco Sebastianutti, Andrea Giusti
We improve upon the results presented in [R. Casadio, et al., Phys. Rev. D 105 (2022) 124026] deriving a quantum-corrected Reissner-Nordström geometry containing an integrable sing…
Quantum Gravitational Corrections in Cosmology
Xavier Calmet, Roberto Casadio, Marco Sebastianutti
We show how to reliably calculate quantum gravitational corrections to cosmological models using the unique effective action formalism for quantum gravity. Our calculations are mod…
The interacting vacuum and tensions: a comparison of theoretical models
Marco Sebastianutti, Natalie B. Hogg, Marco Bruni
We analyse three interacting vacuum dark energy models with the aim of exploring whether the and tensions can be simultaneously resolved in such models. We present the…
Quantum Gravitational Corrections to Particle Creation by Black Holes
Xavier Calmet, Stephen D. H. Hsu, Marco Sebastianutti
We calculate quantum gravitational corrections to the amplitude for the emission of a Hawking particle by a black hole. We show explicitly how the amplitudes depend on quantum corr…
