Density Perturbations in Chain Inflation
We consider the model of “Chain Inflation,” in which the period of inflation in our universe took the form of a long sequence of quantum tunneling events. We find that in the simplest such scenario, in which the tunneling processes are uniform, approximately 104 vacua per e-folding of inflation are required in order that the density perturbations produced are of an acceptable size. We arrive at...
متن کاملPower Spectrum of the Density Perturbations From Smooth Hybrid New Inflation Model
Abstract We numerically investigate density perturbations generated in the smooth hybrid new inflation model, a kind of double inflation model that is designed to reproduce the running spectral index suggested by the WMAP results. We confirm that this model provides the running spectral index within 1σ range of the three year WMAP result. In addition, we find a sharp and strong peak on the spec...
متن کاملOscillations During Inflation and Cosmological Density Perturbations
Adiabatic (curvature) perturbations are produced during a period of cosmological inflation that is driven by a single scalar field, the inflaton. On particle physics grounds – though – it is natural to expect that this scalar field is coupled to other scalar degrees of freedom. This gives rise to oscillations between the perturbation of the inflaton field and the perturbations of the other scal...
متن کاملDensity perturbations and black hole formation in hybrid inflation.
We investigate the recently proposed hybrid inflation models with two stages of inflation. In order to study density perturbations in these models we develop a new method to calculate density perturbations in a system of two scalar fields. We show that density perturbations in hybrid inflation models of the new type can be very large on the scale corresponding to the phase transition between th...
متن کاملSpectrum of Cosmological Perturbations from Multiple-Stage Inflation
Within the context of supersymmetric hybrid inflation, we study a multiple-stage inflationary scenario that can generate a primordial spectrum of adiabatic density perturbations with a break at kb ≃ 0.05 h Mpc. The presence of such a break is supported by the APM galaxy survey data. We consider a specific model within this scenario and confront it with observational data. We reproduce the angul...
