Brane Inflation and Defect Formation
A. C. Davis, P. Brax, C. van de Bruck
Brane inflation and the production of topological defects at the end of the inflationary phase are discussed. After a description of the inflationary setup we discuss the propertie…
The Robustness of n_s < 0.95 in Racetrack Inflation
Ph. Brax, Stephen C. Davis, M. Postma
A spectral index n_s < 0.95 appears to be a generic prediction of racetrack inflation models. Reducing a general racetrack model to a single-field inflation model with a simple pot…
Moduli Fields as Quintessence and the Chameleon
Philippe Brax, Jerome Martin
We consider models where moduli fields are not stabilized and play the role of quintessence. In order to evade gravitational tests, we investigate the possibility that moduli behav…
Brane world supersymmetry, detuning, flipping and orbifolding
Philippe Brax, Zygmunt Lalak
We emphasize the necessity of a delicate interplay between the gauge and gravitational sectors of five-dimensional brane worlds in creating phenomenologically relevant vacua. We di…
Geometrical approach to duality in N=1 supersymmetric theories
Ph Brax, C. Grojean, C. A. Savoy
We investigate the geometry of the moduli spaces of dual electric and magnetic N=1 supersymmetric field theories. Using the SU(N_c) gauge group as a guideline we show that the elec…
A Renormalisation Group Analysis of 2d Freely Decaying Magnetohydrodynamic Turbulence
Ph. Brax
We study two dimensional freely decaying magnetohydrodynamic turbulence. We investigate the time evolution of the probability law of the gauge field and the stream function. Assumi…
