Scalar-tensor cosmologies without screening
Johannes Noller, Luca Santoni, Enrico Trincherini +1
Scalar-tensor theories are frequently only consistent with fifth force constraints in the presence of a screening mechanism, namely in order to suppress an otherwise unacceptably l…
Hairy Black-holes in Shift-symmetric Theories
Paolo Creminelli, Nicolás Loayza, Francesco Serra +2
Scalar hair of black holes in theories with a shift symmetry are constrained by the no-hair theorem of Hui and Nicolis, assuming spherical symmetry, time-independence of the scalar…
To the sphere and back again: de Sitter infrared correlators at NTLO in 1/N
Diana López Nacir, Francisco D. Mazzitelli, Leonardo G. Trombetta
We analyze the infrared behavior of the two and four-point functions for the massless model in Lorentzian de Sitter spacetime, using the expansion. Our approach is bas…
Long distance behavior of -model correlators in de Sitter space and the resummation of secular terms
Diana López Nacir, Francisco D. Mazzitelli, Leonardo G. Trombetta
We analyze the long distance behavior of the two-point functions for an interacting scalar model in de Sitter spacetime. Following our previous work, this behavior is analyz…
Behind Horndeski: Structurally Robust Higher Derivative EFTs
Luca Santoni, Enrico Trincherini, Leonardo G. Trombetta
Higher derivative scalar interactions can give rise to interesting cosmological scenarios. We present a complete classification of such operators that can yield sizeable effects wi…
Nonlocal effective actions in semiclassical gravity: thermal effects in stationary geometries
M. Elías, F. D. Mazzitelli, L. G. Trombetta
We compute the gravitational effective action by integrating out quantum matter fields in a weak gravitational field, using the Schwinger-Keldysh (in-in) formalism. We pay particul…
