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…
A Generic Test of Modified Gravity Models which Emulate Dark Matter
E. O. Kahya, R. P. Woodard
We propose a generic test for models in which gravity is modified to do away with dark matter. These models tend to have gravitons couple to a different metric than ordinary matter…
Avoiding Dark Energy with 1/R Modifications of Gravity
R. P. Woodard
Scalar quintessence seems epicyclic because one can choose the potential to reproduce any cosmology (I review the construction) and because the properties of this scalar seem to ra…
A Leading Logarithm Approximation for Inflationary Quantum Field Theory
R. P. Woodard
During inflation explicit perturbative computations of quantum field theories which contain massless, non-conformal fields exhibit secular effects that grow as powers of the logari…
Quantum Effects during Inflation
R. P. Woodard
The expansion of spacetime alters the energy-time uncertainty principle, allowing virtual particles to persist longer than in flat space. For a given expansion the effect is larges…
The Force of Gravity from a Lagrangian containing Inverse Powers of the Ricci Scalar
M. E. Soussa, R. P. Woodard
We determine the gravitational response to a diffuse source, in a locally de Sitter background, of a class of theories which modify the Einstein-Hilbert action by adding a term pro…
