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,…
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…
Beyond Perturbation Theory in Inflation
Marco Celoria, Paolo Creminelli, Giovanni Tambalo +1
Inflationary perturbations are approximately Gaussian and deviations from Gaussianity are usually calculated using in-in perturbation theory. This method, however, fails for unlike…
Dark-Energy Instabilities induced by Gravitational Waves
Paolo Creminelli, Giovanni Tambalo, Filippo Vernizzi +1
We point out that dark-energy perturbations may become unstable in the presence of a gravitational wave of sufficiently large amplitude. We study this effect for the cubic Horndesk…
Resonant Decay of Gravitational Waves into Dark Energy
Paolo Creminelli, Giovanni Tambalo, Filippo Vernizzi +1
We study the decay of gravitational waves into dark energy fluctuations , taking into account the large occupation numbers. We describe dark energy using the effective field the…
Gravitational Wave Decay into Dark Energy
Paolo Creminelli, Matthew Lewandowski, Giovanni Tambalo +1
We study the decay of gravitational waves into dark energy fluctuations , through the processes and , made possible by the spontaneous breaking of Lorentz inv…
