Do Type-Ia Supernovae Constrain the Total Equation of State?
William Komp
In this paper, we consider a couple of alternative dark energy models using the total equation of state of the cosmological fluid, $\wt$. These models are fit to the recent type-Ia…
A Sudden Gravitational Transition
Robert R. Caldwell, William Komp, Leonard Parker +1
We investigate the properties of a cosmological scenario which undergoes a gravitational phase transition at late times. In this scenario, the Universe evolves according to general…
Nonlinear Gravity Theories in the Metric and Palatini Formalisms
Gonzalo J. Olmo, William Komp
We study nonlinear gravity theories in both the metric and the Palatini (metric-affine) formalisms. The nonlinear character of the gravity lagrangian in the metric formalism causes…
Cosmological Acceleration Through Transition to Constant Scalar Curvature
Leonard Parker, William Komp, Daniel A. T. Vanzella
As shown by Parker and Raval, quantum field theory in curved spacetime gives a possible mechanism for explaining the observed recent acceleration of the universe. This mechanism, w…
