A Model for Cosmic Self-Acceleration
Gregory Gabadadze
We discuss a model which gives rise to cosmic self-acceleration due to modified gravity. Improvements introduced by this approach are the following: In the coordinate system common…
Domain Walls As Probes Of Gravity
Gia Dvali, Gregory Gabadadze, Oriol Pujolas +1
We show that domain walls are probes that enable one to distinguish large-distance modified gravity from general relativity (GR) at short distances. For example, low-tension domain…
Perturbations of Self-Accelerated Universe
Cedric Deffayet, Gregory Gabadadze, Alberto Iglesias
We discuss small perturbations on the self-accelerated solution of the DGP model, and argue that claims of instability of the solution that are based on linearized calculations are…
Resonance in Asymmetric Warped Geometry
Gregory Gabadadze, Luca Grisa, Yanwen Shang
We study the spectrum of an asymmetric warped braneworld model with different AdS curvatures on either side of the brane. In addition to the RS-like modes we find a resonance state…
(De)coupling Limit of DGP
Gregory Gabadadze, Alberto Iglesias
We investigate the decoupling limit in the DGP model of gravity by studying its nonlinear equations of motion. We show that, unlike 4D massive gravity, the limiting theory does not…
