Parametric Amplification of Metric Fluctuations During Reheating in Two Field Models
It was recently suggested [1] that parametric resonance during the reheating phase of an inflationary Universe [2–4] may lead to an exponential amplification of superHubble scale gravitational fluctuations. If true, this would affect the usual predictions of inflationary models for observables such as the matter power spectrum and the spectrum of cosmic microwave anisotropies. In particular, it...
متن کاملParametric Amplification of Gravitational Fluctuations During Reheating
We demonstrate that cosmological perturbations can undergo amplification by parametric resonance during the preheating period following inflation, even on scales larger than the Hubble radius, without violating causality. A unified description of gravitational and matter fluctuations is crucial in order to determine the strength of the instability. To extract specific signatures of the oscillat...
متن کاملParametric amplification of metric fluctuations through a bouncing phase
We clarify the properties of the behavior of classical cosmological perturbations when the Universe experiences a bounce. This is done in the simplest possible case for which gravity is described by general relativity and the matter content has a single component, namely a scalar field in a closed geometry. We show in particular that the spectrum of scalar perturbations can be affected by the b...
متن کاملInflaton field fluctuations from gauge - invariant metric fluctuations during inflation
The evolution of the inflaton field fluctuations from gauge-invariant metric fluctuations is discussed. In particular, the case of a symmetric φ c-exponential potential is analyzed.
متن کاملGauge invariant metric perturbations during reheating
The possible amplification of gauge invariant metric fluctuations in the infrared sector are very important during reheating stage of inflation. In this stage the inflaton field oscillates around the minimum of the scalar potential. The evolution for the super Hubble scales gauge invariant metric fluctuations can be studied by means of the Bardeen parameter. For a massive scalar field with pote...
