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…
Transitions Between de Sitter Minima
Puneet Batra, Matthew Kleban
We investigate the cosmological signatures of instantons mediating tunneling between de Sitter minima. For generic potentials the Coleman-de Luccia instanton does not necessarily e…
Predictive Power of Strong Coupling in Theories with Large Distance Modified Gravity
Gia Dvali
We consider theories that modify gravity at cosmological distances, and show that any such theory must exhibit a strong coupling phenomenon, or else it is either inconsistent or is…
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…
Quantum fluctuations in the DGP model and the size of the cross-over scale
Oriol Pujolas
The Dvali-Gabadadze-Porrati model introduces a parameter, the cross-over scale , setting the scale where higher dimensional effects are important. In order to agree with obser…
Black Holes with Quantum Massive Spin-2 Hair
Gia Dvali
We show that black holes can posses a long range quantum mechanical hair associated with a massive spin-2 field, which can be detected by a stringy generalization of the Aharovon-B…
