Acausal exact vacuum solutions in nonlocal gravity
Zhe Zhao, Leonardo Modesto, Cosimo Bambi
Nonlocal gravity is a promising super-renormalizable or finite quantum gravity theory consistent with unitarity. In this paper, we focus on the classical equations of motion and ex…
Ultraviolet completion of the inflationary paradigm
Leonardo Modesto, Lorenzo Orlando
After an exhaustive introduction highlighting the strengths and weaknesses of the non-local models proposed so far as ultraviolet completions of the Starobinsky theory, we propose…
Stable Wormholes in Conformal Gravity
Mariano Cadoni, Leonardo Modesto, Mirko Pitzalis +1
We present a class of Lorentzian traversable wormholes in conformal gravity, constructed via Weyl rescaling of Minkowski spacetime. As a result, these wormholes are solutions of ev…
Graviton propagator in loop quantum gravity
Eugenio Bianchi, Leonardo Modesto, Carlo Rovelli +1
We compute some components of the graviton propagator in loop quantum gravity, using the spinfoam formalism, up to some second order terms in the expansion parameter.
