Asymptotic safety in an interacting system of gravity and scalar matter
Pietro Donà, Astrid Eichhorn, Peter Labus +1
Asymptotic safety is an attractive scenario for the dynamics of quantum spacetime. Here, we work from a phenomenologically motivated point of view and emphasize that a viable dynam…
Non-Perturbative Yang-Mills Condensate as Dark Energy
Pietro Donà, Antonino Marcianò, Yang Zhang +1
Models based on Yang-Mills condensate (YMC) have been advocated in the literature and claimed to be successful candidates to explain dark energy. Several instantiations of this sim…
Scattering amplitudes in super-renormalizable gravity
Pietro Donà, Stefano Giaccari, Leonardo Modesto +2
We explicitly compute the tree-level on-shell four-graviton amplitudes in four, five and six dimensions for local and weakly nonlocal gravitational theories that are quadratic in b…
