Quantum State of the Asymptotic Gravity Field from BRST Quantization
Xavier Calmet, Stephen D. H. Hsu
We derive the quantum state of the asymptotic linearized gravity field of a compact energy source, using BRST quantization. Barnich has previously derived the quantum state of the…
Leading order effective operators in quantum gravity
Tommaso Antonelli, Xavier Calmet, Stephen D. H. Hsu
We explore the nature of higher dimensional operators generated by quantum gravity. Calculating the tree-level and one-loop effective operators generated by graviton exchange betwe…
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…
Detecting milli-Hz gravitational waves with optical resonators
G. Barontini, X. Calmet, V. Guarrera +2
We propose a gravitational wave detector based on ultrastable optical cavities enabling the detection of gravitational wave signals in the mostly unexplored Hz frequenc…
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…
The Weak Gravity Conjecture in the Vilkovisky-DeWitt Effective Action of Quantum Gravity
Tommaso Antonelli, Xavier Calmet
The Weak Gravity Conjecture states that in any consistent theory of quantum gravity in the landscape of string theory, the repulsive force mediated by a U(1) gauge field must be st…
