On the Asymptotic Causal Structure in Gravitational EFTs
Bruno Bucciotti, Paolo Creminelli, Alessandro Longo +2
It is usually assumed that a healthy EFT should not allow superluminal propagation. In the presence of gravity, however, the notion of superluminality becomes subtle, since there i…
Analyticity and positivity of Green's functions without Lorentz
Paolo Creminelli, Alessandro Longo, Borna Salehian +1
We study the properties imposed by microcausality and positivity on the retarded two-point Green's function in a theory with spontaneous breaking of Lorentz invariance. We assume i…
Large -point Functions in Resonant Inflation
Paolo Creminelli, Sébastien Renaux-Petel, Giovanni Tambalo +1
We investigate a qualitatively new regime of inflationary models with small and rapid oscillations in the potential-resonant non-Gaussianity. In contrast to the standard scenario,…
The Memory of Primordial Gravitational Waves
Paolo Creminelli, Filippo Vernizzi
Primordial gravitational waves, after they enter the horizon and decay away, leave a residual displacement in test particles: a memory, in analogy with gravitational waves generate…
Positivity bounds on electromagnetic properties of media
Paolo Creminelli, Oliver Janssen, Borna Salehian +1
We study the constraints imposed on the electromagnetic response of general media by microcausality (commutators of local fields vanish outside the light cone) and positivity of th…
Non-perturbative Wavefunction of the Universe in Inflation with (Resonant) Features
Paolo Creminelli, Sébastien Renaux-Petel, Giovanni Tambalo +1
We study the statistics of scalar perturbations in models of inflation with small and rapid oscillations in the inflaton potential (resonant non-Gaussianity). We do so by deriving…
