Dynamical solution of supergravity
Pierre Binetruy, Misao Sasaki, Kunihito Uzawa
We present a class of dynamical solutions for an intersecting D4-D8 brane system in ten-dimensional type IIA supergravity. The dynamical solutions reduces to a static warped AdS_6…
Dynamical D4-D8 and D3-D7 branes in supergravity
Pierre Binetruy, Misao Sasaki, Kunihito Uzawa
We present a class of dynamical solutions for intersecting D4-D8 and D3-D7 brane systems in ten-dimensional type IIA and IIB supergravity. We discuss if these solutions can be reco…
Local Axion Cosmic Strings from Superstrings
Stephen C. Davis, Pierre Binetruy, Anne-Christine Davis
Axionic cosmic string solutions are investigated in a superstring motivated model with a pseudo-anomalous U(1) gauge symmetry. The inclusion of a gauge field and spatially varying…
Models for the Brane-Bulk Interaction: Toward Understanding Braneworld Cosmological Perturbation
Pierre Binetruy, Martin Bucher, Carla Carvalho
Using some simple toy models, we explore the nature of the brane-bulk interaction for cosmological models with a large extra dimension. We are in particular interested in understan…
Fayet-Iliopoulos Terms in Supergravity and Cosmology
Pierre Binetruy, Gia Dvali, Renata Kallosh +1
We clarify the structure of N=1 supergravity in 1+3 dimensions with constant FI terms. The FI terms induce non-vanishing R-charges for the fermions and the superpotential. Therefor…
