Microscopic entropy of de Sitter spacetime and entropic solution to the old cosmological constant problem
Mariano Cadoni, Lorenzo Herres, Lorenzo Orlando +1
We study the role of Weyl symmetry breaking in conformal gravity and the residual scale symmetry of Einstein gravity. The corresponding action is characterized by a dimensionless c…

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…

Eikonal, nonlocality and regular black holes
Mariano Cadoni, Lorenzo Herres, Leonardo Modesto +2
We investigate the leading gravitational eikonal in nonlocal dimensional theories of gravity. We analyze the simplest cases of massless and massive scalar scatt…
