Scalar perturbations from brane-world inflation
K. Koyama, D. Langlois, R. Maartens +1
We investigate the scalar metric perturbations about a de Sitter brane universe in a 5-dimensional anti de Sitter bulk. We compare the master-variable formalism, describing metric…
Induced gravity with a non-minimally coupled scalar field on the brane
Mariam Bouhmadi-Lopez, David Wands
We present the four-dimensional equations on a brane with a scalar field non-minimally coupled to the induced Ricci curvature, embedded in a five-dimensional bulk with a cosmologic…
Gravitational waves from brane-world inflation with induced gravity
Mariam Bouhmadi-Lopez, Roy Maartens, David Wands
We calculate the amplitude of gravitational waves produced by inflation on a de Sitter brane embedded in five-dimensional anti-de Sitter bulk spacetime, extending previous calculat…
