Inflation on a single brane - exact solutions
Rachael M. Hawkins, James E. Lidsey
Algorithms are developed for generating a class of exact braneworld cosmologies, where a self-interacting scalar field is confined to a positive-tension brane embedded in a bulk co…
Supersymmetric Quantization of Anisotropic Scalar-Tensor Cosmologies
James E. Lidsey, P. Vargas Moniz
In this paper we show that the spatially homogeneous Bianchi type I and Kantowski-Sachs cosmologies derived from the Brans-Dicke theory of gravity admit a supersymmetric extension…
Supergravity Brane Cosmologies
James E. Lidsey
Solitonic brane cosmologies are found where the world-volume is curved due to the evolution of the dilaton field on the brane. In many cases, these may be related to the solitonic…
Steep inflation: ending braneworld inflation by gravitational particle production
Edmund J Copeland, Andrew R Liddle, James E Lidsey
We propose a scenario for inflation based upon the braneworld picture, in which high-energy corrections to the Friedmann equation permit inflation to take place with potentials ord…
Cyclical Behaviour in Early Universe Cosmologies
Andrew P. Billyard, Alan A. Coley, James E. Lidsey
We study early universe cosmologies derived from a scalar-tensor action containing cosmological constant terms and massless fields. The governing equations can be written as a dyna…
