Non-commutative Power-law Inflation: Mode Equation and Spectra Index
Following an elegant approach that merge the effects of the stringy spacetime uncertainty relation into primordial perturbations suggested by Brandenberger and Ho, we show the mode equation up to the first order of non-commutative parameter. A new approximation is provided to calculate the mode functions analytically in the non-commutative power-law inflation models. It turns out that non-commu...
متن کاملEffect of the length of inflation on angular TT and TE power spectra in power-law inflation
The effect of the length of inflation on the power spectra of scalar and tensor perturbations is estimated using the power-law inflation model with a scale factor of a(η) = (η) = t. Considering various pre-inflation models with radiation-dominated or scalar matter-dominated periods before inflation in combination with two matching conditions, the temperature angular power spectrum (TT) and tem...
متن کاملInflation on a non-commutative space–time
Article history: Received 24 April 2015 Received in revised form 9 June 2015 Accepted 11 June 2015 Available online 16 June 2015 Editor: M. Trodden We study inflation on a non-commutative space–time within the framework of enveloping algebra approach which allows for a consistent formulation of general relativity and of the standard model of particle physics. We show that within this framework,...
متن کاملPower-Law Inflation from the Rolling Tachyon
Modeling the potential by an inverse square law in terms of the tachyon field (V (T ) = βT−2) we find exact solution for spatially flat isotropic universe. We show that for β > 2 √ 3/3 the model undergoes power-law inflation. A way to construct other exact solutions is specified and exemplified. Several interesting attempts to reconcile the inflationary paradigm with string theories have result...
متن کاملPower Spectra in Spacetime Noncommutative Inflation
String/M theory inspires an uncertainty relation between space and time which deviates from general relativity. It is possible to explore this deviation from cosmological observations, in particular from the CMB fluctuation spectrum. This paper extends some previous observations to more general inflation schemes, we find that the noncommutative spacetime effects always suppress the power spectr...
