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…
Perfect fluid brane-world model
M. Bouhmadi-Lopez, P. F. Gonzalez-Diaz, A. Zhuk
By considering 5--dimensional cosmological models with a bulk filled with a perfect fluid and a cosmological constant, we have found regular instantonic solution which is free from…
