Brane-world inflation: slow-roll corrections to the spectral index
Kazuya Koyama, Andrew Mennim, David Wands
We quantify the slow-roll corrections to primordial density perturbations arising from inflation driven by a four-dimensional scalar field with a monomial potential in a five-dimen…
Primordial perturbations from slow-roll inflation on a brane
Kazuya Koyama, Andrew Mennim, V. A. Rubakov +2
In this paper we quantise scalar perturbations in a Randall-Sundrum-type model of inflation where the inflaton field is confined to a single brane embedded in five-dimensional anti…
Coupled bulk and brane fields about a de Sitter brane
Antonio Cardoso, Kazuya Koyama, Andrew Mennim +2
We consider the evolution of a bulk scalar field in anti-de Sitter (AdS) spacetime linearly coupled to a scalar field on a de Sitter boundary brane. We present results of a spectra…
Coupled boundary and bulk fields in anti-de Sitter
Kazuya Koyama, Andrew Mennim, David Wands
We investigate the dynamics of a boundary field coupled to a bulk field with a linear coupling in an anti-de Sitter bulk spacetime bounded by a Minkowski (Randall-Sundrum) brane. A…
Linearized self-forces for branes
Richard A. Battye, Brandon Carter, Andrew Mennim
We compute the regularized force density and renormalized action due to fields of external origin coupled to a brane of arbitrary dimension in a spacetime of any dimension. Specifi…
Multiple-scales analysis of cosmological perturbations in brane-worlds
Richard A. Battye, Andrew Mennim
We present a new approximation method for solving the equations of motion for cosmological tensor perturbations in a Randall-Sundrum brane-world model of the type with one brane in…
