Thawing quintessence with a nearly flat potential
Robert J. Scherrer, A. A. Sen
The thawing quintessence model with a nearly flat potential provides a natural mechanism to produce an equation of state parameter, w, close to -1 today. We examine the behavior of…
The Return of a Static Universe and the End of Cosmology
Lawrence M. Krauss, Robert J. Scherrer
We demonstrate that as we extrapolate the current CDM universe forward in time, all evidence of the Hubble expansion will disappear, so that observers in our "island universe" w…
The Weak Energy Condition and the Expansion History of the Universe
A. A. Sen, Robert J. Scherrer
We examine flat models containing a dark matter component and an arbitrary dark energy component, subject only to the constraint that the dark energy satisfies the weak energy cond…
Radiation can never again dominate Matter in a Vacuum Dominated Universe
Lawrence M. Krauss, Robert J. Scherrer
We demonstrate that in a vacuum-energy-dominated expansion phase, surprisingly neither the decay of matter nor matter-antimatter annihilation into relativistic particles can ever c…
