Are there ALPs in the asymptotically safe landscape?
Gustavo P. de Brito, Astrid Eichhorn, Rafael R. Lino dos Santos
We investigate axion-like particles (ALPs) in the context of asymptotically safe gravity-matter systems. The ALP-photon interaction, which facilitates experimental searches for ALP…
The weak-gravity bound and the need for spin in asymptotically safe matter-gravity models
Gustavo P. de Brito, Astrid Eichhorn, Rafael Robson Lino dos Santos
We discover a weak-gravity bound in scalar-gravity systems in the asymptotic-safety paradigm. The weak-gravity bound arises in these systems under the approximations we make, when…
Can quantum fluctuations differentiate between standard and unimodular gravity?
Gustavo P. de Brito, Oleg Melichev, Roberto Percacci +1
We formally prove the existence of a quantization procedure that makes the path integral of a general diffeomorphism-invariant theory of gravity, with fixed total spacetime volume,…
