Second-Order Cosmological Perturbations from Inflation
V. Acquaviva, N. Bartolo, S. Matarrese +1
We present the first computation of the cosmological perturbations generated during inflation up to second order in deviations from the homogeneous background solution. Our results…
An Observational Test of Two-field Inflation
David Wands, Nicola Bartolo, Sabino Matarrese +1
We study adiabatic and isocurvature perturbation spectra produced by a period of cosmological inflation driven by two scalar fields. We show that there exists a model-independent c…
The simplest curvaton model
N Bartolo, Andrew R Liddle
We analyze the simplest possible realization of the curvaton scenario, where a nearly scale-invariant spectrum of adiabatic perturbations is generated by conversion of an isocurvat…
