Non-Gaussianity from Inflation
Correlated adiabatic and isocurvature perturbation modes are produced during inflation through an oscillation mechanism when extra scalar degrees of freedom -other than the inflaton field are present. We show that this correlation generically leads to sizeable non-Gaussian features both in the adiabatic and isocurvature perturbations. The nonGaussianity is first generated by large non-lineariti...
متن کاملEnhancement of Non-Gaussianity after Inflation
We study the evolution of cosmological perturbations on large scales, up to second order, for a perfect fluid with generic equation of state. Taking advantage of super-horizon conservation laws, it is possible to follow the evolution of the non-Gaussianity of perturbations through the different stages after inflation. We find that a large non-linearity is generated by the gravitational dynamics...
متن کاملTwo-Stage Inflation as a Solution to the Initial Condition Problem of Hybrid Inflation
We address the issue of fine-tuning of the initial field configuration that can lead to hybrid inflation in the context of global supersymmetry. This problem is generated by the difference between the energy scale at which the Universe emerges from the Planck era and the inflationary scale implied by the COBE observations: V 1/4 ∼ 10−3mPl. We propose a scenario with two stages of inflation. The...
متن کاملNon–Gaussianity from Inflation: Theory and Observations
This is a review of models of inflation and of their predictions for the primordial non–Gaussianity in the density perturbations which are thought to be at the origin of structures in the Universe. Non–Gaussianity emerges as a key observable to discriminate among competing scenarios for the generation of cosmological perturbations and is one of the primary targets of present and future Cosmic M...
متن کاملNon-Gaussianity in braneworld and tachyon inflation
We calculate the bispectrum of single-field braneworld inflation, triggered by either an ordinary scalar field or a cosmological tachyon, by means of a gradient expansion of large-scale non-linear perturbations coupled to stochastic dynamics. The resulting effect is identical to that for single-field 4D standard inflation, the nonlinearity parameter being proportional to the scalar spectral ind...
