Gravity Gets There First with Dark Matter Emulators
S. Desai, E. O. Kahya, R. P. Woodard
We discuss the implications for gravity wave detectors of a class of modified gravity theories which dispense with the need for dark matter. These models, which are known as Dark M…
Cosmology is not a Renormalization Group Flow
R. P. Woodard
A critical examination is made of two simple implementations of the idea that cosmology can be viewed as a renormalization group flow. Both implementations are shown to fail when a…
Two loop stress-energy tensor for inflationary scalar electrodynamics
Tomislav Prokopec, Nicholas C. Tsamis, Richard P. Woodard
We calculate the expectation value of the coincident product of two field strength tensors at two loop order in scalar electrodynamics on de Sitter background. The result agrees wi…
Cosmology with a long-range repulsive force
William H. Kinney, Martina Brisudova, Richard Woodard
We discuss the properties of a cosmology dominated by a charged scalar field with a repulsive, long-range self-interaction. The interaction, in the form of a vector field with a ti…
