Parametric Amplification of Density Perturbation in the Oscillating inflation
We study the adiabatic density perturbation in the oscillating inflation, proposed by Damour and Mukhanov. The recent study of the cosmological perturbation during reheating shows that the adiabatic fluctuation behaves like as the perfect fluid and no significant amplification occurs on super-horizon scales. In the oscillating inflation, however, the accelerated expansion takes place during the...
متن کاملDensity 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 کاملCosmological Density Perturbations From A Quantum Gravitational Model Of Inflation
We derive the implications for anisotropies in the cosmic microwave background following from a model of inflation in which a bare cosmological constant is gradually screened by an infrared process in quantum gravity. The model predicts that the amplitude of scalar perturbations is AS = (2.0± .2)× 10−5, that the tensor-to-scalar ratio is r ≈ 1.7× 10−3, and that the scalar and tensor spectral in...
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 کاملGeneration of density perturbations at the end of inflation
1550-7998=20 Recently a mechanism was proposed whereby the primordial density perturbations are generated at the end of inflation. We continue the analysis of the proposed model of this mechanism and calculate the maximum extent to which the density perturbations produced via this model can dominate over those of the standard inflationary paradigm. In addition, we provide a straightforward vari...
