Inflationary magnetogenesis from dynamical gauge couplings
The evolution of the gauge coupling is modelled using a scalar degree of freedom whose homogeneous and inhomogeneous modes evolve from an ordinary inflationary phase to the subsequent epochs. Depending upon various parameters (scalar mass, curvature scale at the end of inflation and at the onset of the radiation epoch), the two-point function of the magnetic inhomogeneities grows during the de ...
متن کاملConstraints on Generalized Inflationary Cosmologies
We consider cosmologies having an inflationary period during which the Robertson-Walker scale factor is an arbitrary function of time satisfying /~ > 0 (not necessarily an exponential). We show that any such inflationary period will produce long-wavelength gravitational waves which can affect present observations of the microwave background. Using present bounds on the quadrupole anisotropy we ...
متن کاملComplete WMAP Constraints on Bandlimited Inflationary Features
Using a principal component (PC) basis that accommodates order unity features in the slow roll parameters as fine as 1/10 of a decade across more than 2 decades of the inflationary expansion, we test slow roll and single field inflation with the WMAP7 data. Detection of any non-zero component would represent a violation of ordinary slow roll and indicate a feature in the inflaton potential or s...
متن کاملInflationary Constraints on Type IIA String Theory
We prove that inflation is forbidden in the most well understood class of semi-realistic type IIA string compactifications: Calabi-Yau compactifications with only standard NS-NS 3-form flux, R-R fluxes, D6-branes and O6-planes at large volume and small string coupling. With these ingredients, the first slow-roll parameter satisfies ǫ ≥ 27 13 whenever V > 0, ruling out both inflation (including ...
متن کاملKinematic Constraints to the Key Inflationary Observables
The observables T/S and n−1 are key to testing and understanding inflation. (T , S, and n−1 respectively quantify the gravity-wave and density-perturbation contributions to CMB anisotropy and the deviation of the density perturbations from the scale-invariant form.) Absent a standard model, there is no definite prediction for, or relation between, T/S and n − 1. By reformulating the equations g...
