Inflationary attractors and perturbation spectra in generally coupled gravity.
A generic outcome of theories with scalar-tensor coupling is the existence of inflationary attractors, either power-law or de Sitter. The fluctuations arising during this phase are Gaussian and their spectrum depends on the wavenumber k according to the power-law k 1/(1−p) , where p is the inflationary power-law exponent. We investigate to which extent these properties depend on the coupling fu...
متن کاملInflationary parameters and primordial perturbation spectra ⋆
I discuss how parameters describing inflation in the very early universe may be related to primordial perturbation spectra. Precision observations of anisotropies in the cosmic microwave background (CMB) such as those provided by the WMAP satellite offer an unprecedented window onto the physics of the very early universe. To theorists exploring speculative models of physics at high energies, th...
متن کاملPost - COBE predictions for Inflationary Gravity Wave and Density Perturbation spectra
We assess the relative contribution to the COBE-measured microwave anisotropy arising both from relic gravity waves as well as primordial density perturbations originating during inflation. We show that the gravity wave contribution to the CMBR anisotropy depends sensitively upon n – the primordial spectral index (|δ k | 2 ∝ k n), increasing as n deviates from a Harrison-Zeldovich spectrum (n =...
متن کاملPlanck scale inflationary spectra from quantum gravity
We derive the semiclassical evolution of massless minimally coupled scalar matter in the de Sitter space-time from the Born-Oppenheimer reduction of the Wheeler-DeWitt equation. We show that the dynamics of trans-Planckian modes can be cast in the form of an effective modified dispersion relation and that high energy corrections in the power spectrum of the cosmic microwave background radiation...
متن کاملInflationary quasiscale-invariant attractors
In a series of recent papers Kallosh, Linde, and collaborators provide a unified description of single-field inflation with several types of potentials ranging from power law to supergravity, in terms of just one parameter α. These so-called α attractors predict a spectral index ns and a tensor-to-scalar ratio r, which are fully compatible with the latest Planck data. The only common feature of...
