Extended Slow-Roll Conditions and Rapid-Roll Conditions

چکیده
We derive slow-roll conditions for a scalar field which is non-minimally coupled with gravity in a consistent manner and express spectral indices of scalar/tensor perturbations in terms of the slow-roll parameters. The conformal invariance of the curvature perturbation is proved without linear approximations. Rapid-roll conditions are also derived, and the relation with the slow-roll conditions is discussed.

The Slow-Roll and Rapid-Roll Conditions in The Space-like Vector Field Scenario
In this note we derive the slow-roll and rapid-roll conditions for the minimally and nonminimally coupled space-like vector fields. The function f(B) represents the non-minimal coupling effect between vector fields and gravity, the f = 0 case is the minimal coupling case. For a clear comparison with scalar field, we define a new function F = ±B2/12+f(B2) where B = AμA , Aμ is the “comoving” vec...
متن کاملExtended Slow-Roll Conditions and Primordial Fluctuations: Multiple Scalar Fields and Generalized Gravity
As an extension of our previous study, we derive slow-roll conditions for multiple scalar fields which are non-minimally coupled with gravity and for generalized gravity theories of the form f(φ,R). We provide simple formulae of the spectral indices of scalar/tensor perturbations in terms of the slow-roll parameters.

متن کاملCosmological Perturbations and Non-Gaussianities in Hořava-Lifshitz Gravity
We investigate cosmological perturbations and non-gaussianities in Hořava-Lifshitz theory of gravitation. In the UV limit, the scalar perturbation in Hořava theory is naturally scale-invariant, ignoring the details of the expansion of the universe. Thus one may relax the exponential inflation and the slow-roll conditions for the inflaton field. Moreover, in the absence of slow-roll conditions, ...
متن کاملGeneralized Slow Roll for Non-Canonical Kinetic Terms
We show that the generalized slow-roll approach for calculating the power spectrum where the inflationary slow roll parameters are neither small nor slowly varying can be readily extended to models with non-canonical kinetic terms in the inflaton action. For example, rapid sound speed variations can arise in DBI models with features in the warp factor leading to features in the power spectrum. ...
متن کاملWKB approximation for inflationary cosmological perturbations
A new method for predicting inflationary cosmological perturbations, based on the Wentzel-KramersBrillouin ~WKB! approximation, is presented. A general expression for the WKB scalar and tensor power spectra is derived. The main advantage of the new scheme of approximation is that it is valid even if the slow-roll conditions are violated. The method is applied to power-law inflation, which allow...
