Embedding Dark Energy in Supergravity
Philippe Brax
We give a brief overview of some of the constraints on the embedding of dark energy in supergravity.
Detecting Chameleons through Casimir Force Measurements
Philippe Brax, Carsten van de Bruck, Anne-Christine Davis +2
The best laboratory constraints on strongly coupled chameleon fields come not from tests of gravity per se but from precision measurements of the Casimir force. The chameleonic for…
Testing Chameleon Theories with Light Propagating through a Magnetic Field
P. Brax, C. van de Bruck, A. C. Davis +2
It was recently argued that the observed PVLAS anomaly can be explained by chameleon field theories in which large deviations from Newton's law can be avoided. Here we present the…
Compatibility of the chameleon-field model with fifth-force experiments, cosmology, and PVLAS and CAST results
Ph. Brax, C. van de Bruck, A. -C. Davis
We analyse the PVLAS results using a chameleon field whose properties depend on the environment. We find that, assuming a runaway bare potential and a universal coupling to…
Brane World Moduli and the CMB
Ph. Brax, C. van de Bruck, A. -C. Davis +1
The evolution of moduli fields, which naturally appear in higher dimensional models such as brane worlds, and their effects on the anisotropies of the cosmological microwave backgr…
Branes at low energy
Ph. Brax, C. van de Bruck, A. -C. Davis +1
Brane models at low energy are described by an effective action involving gravity and two moduli fields associated with the brane positions. The scalar-tensor nature of the effecti…
