Frame-Independent Calculation of Spectral Indices from Inflation
نویسنده
چکیده
Spectral indices from models of inflation which incorporate a Generalized Einstein Theory (GET) gravity sector are calculated to first order in a slow-roll expansion. By quantizing a suitably-generalized measure of the intrinsic curvature perturbation, the spectral indices as calculated in the Jordan frame now match those as calculated following a conformal transformation, in the Einstein frame. PACS numbers: 98.80C, 04.50

Primordial spectral indices from generalized Einstein theories.
Primordial spectral indices are calculated to second order in slow-roll parameters for three closely-related models of inflation, all of which contain a scalar field non-minimally coupled to the Ricci curvature scalar. In most cases, ns may be written as a function of the nonminimal curvature coupling strength ξ alone, with ns(ξ) ≤ 1, although the constraints on ξ differ greatly between ‘new in...

We present a new approximation scheme that allows us to increase the accuracy of analytical predictions of the power spectra of inflationary perturbations for two specific classes of inflationary models. Among these models are chaotic inflation with a monomial potential, power-law inflation and natural inflation (inflation at a maximum). After reviewing the established first order results we ca...

متن کاملInflation Determinants in Low and High Frequencies: An Implication of Spectral Analysis to Iran
There is no evidence that previous studies, available to Iran’s inflation literature, have used spectral methodology to analyze a possible relationship between inflation and its main determinants within a specific period. Accordingly, the present study investigates the effects of money growth, real output growth, output gap and interest rate changes on inflation at low and high frequencies...
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...
