Asymmetric brane-worlds with induced gravity
Laszlo Gergely, Roy Maartens
The Randall-Sundrum scenario, with a 1+3-dimensional brane in a 5-dimensional bulk spacetime, can be generalized in various ways. We consider the case where the Z2-symmetry at the…
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…
Asymmetric radiating brane-world
Laszlo Gergely, Emily Leeper, Roy Maartens
At high energies on a cosmological brane of Randall-Sundrum type, particle interactions can produce gravitons that are emitted into the bulk and that can feed a bulk black hole. We…
Detecting extra dimensions with gravity wave spectroscopy: the black string brane-world
Sanjeev S. Seahra, Chris Clarkson, Roy Maartens
Using the black string between two branes as a model of a brane-world black hole, we compute the gravity wave perturbations and identify the features arising from the additional po…
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…
Loop Quantum Gravity and the Cyclic Universe
Martin Bojowald, Roy Maartens, Parampreet Singh
Loop quantum gravity introduces strong non-perturbative modifications to the dynamical equations in the semi-classical regime, which are responsible for various novel effects, incl…
