Inflationary potentials yielding constant scalar perturbation spectral indices
Alberto Vallinotto, Edmund J. Copeland, Edward W. Kolb +2
We explore the types of slow-roll inflationary potentials that result in scalar perturbations with a constant spectral index, i.e., perturbations that may be described by a single…
On the reheating stage after inflation
Edward W. Kolb, Alessio Notari, Antonio Riotto
We point out that inflaton decay products acquire plasma masses during the reheating phase following inflation. The plasma masses may render inflaton decay kinematicaly forbidden,…
Lorentz invariance violation in top-down scenarios of ultrahigh energy cosmic ray creation
James R. Chisholm, Edward W. Kolb
The violation of Lorentz invariance (LI) has been invoked in a number of ways to explain issues dealing with ultrahigh energy cosmic ray (UHECR) production and propagation. These t…
The Radionactive Universe
Edward W. Kolb, Geraldine Servant, Tim M. P. Tait
In a large class of extra-dimensional models, a scalar degree of freedom known as the radion is long-lived, or even stable, on cosmological scales. In this paper we investigate the…
WMAPping inflationary physics
William H. Kinney, Edward W. Kolb, Alessandro Melchiorri +1
We extract parameters relevant for distinguishing among single-field inflation models from the Wilkinson Microwave Anisotropy Probe (WMAP) data set, and from a combination of the W…
