The Largest Scale We Can Detect in the Universe and the Inflation

From the damping of the Cosmic Microwave Background Radiation (CMB) anisotropy power spectrum at large scale and the recent accelerating expansion of the Universe, we find that, there may be a largest scale which we can detect in the Universe. From this, we can get the inflation parameters as spectrum index n s of the initial scalar spectrum, e-fold N , Hubble parameter H, the ratio of tensor a...

Inflation in minimal left-right symmetric model with spontaneous D-parity breaking

It is now widely believed that the Universe has gone through a period of inflation [1] at the earliest moment of its history. Inflation is required to explain finely tuned initial conditions of the standard hot big bang cosmology, as well as to solve many cosmological problems such as homogeneity, isotropy and flatness of the observable Universe. Moreover, it is predicted that during inflation ...

Inflationary potentials yielding constant scalar perturbation spectral indices

Inflation, a cornerstone of the modern framework for understanding the early universe @1,2#, predicts the initial conditions for the formation of structure and the cosmic microwave background ~CMB! anisotropies. During inflation, the primordial scalar ~density! and tensor ~gravitational wave! perturbations generated by quantum fluctuations are redshifted beyond the Hubble radius, becoming froze...

Inflationary Potential Reconstruction for a WMAP Running Power Spectrum

The WMAP measurement of the CMB temperature anisotropy is intriguingly consistent with a larger running of the inflationary scalar spectral index than would be expected for single-field inflation. We revisit the issue of a large running spectral index, first by reexamining the evidence from the data, and then by reconstructing the inflationary potential, using a new method based upon the Hamilt...
