The Robustness of n_s < 0.95 in Racetrack Inflation
Ph. Brax, Stephen C. Davis, M. Postma
A spectral index n_s < 0.95 appears to be a generic prediction of racetrack inflation models. Reducing a general racetrack model to a single-field inflation model with a simple pot…
Solar System Constraints on f(G) Dark Energy
Stephen C. Davis
Corrections to solar system gravity are derived for f(G) gravity theories, in which a function of the Gauss-Bonnet curvature term is added to the gravitational action. Their effect…
Solar System Constraints on Gauss-Bonnet Dark Energy
Stephen C. Davis
Quadratic curvature Gauss-Bonnet gravity may be the solution to the dark energy problem, but a large coupling strength is required. This can lead to conflict with laboratory and pl…
Solar System Constraints on Gauss-Bonnet Mediated Dark Energy
Luca Amendola, Christos Charmousis, Stephen C. Davis
Although the Gauss-Bonnet term is a topological invariant for general relativity, it couples naturally to a quintessence scalar field, modifying gravity at solar system scales. We…
