Chameleon foreCAST
Philippe Brax, Axel Lindner, Konstantin Zioutas
Dark energy models, such as the chameleon, where the acceleration of the expansion of the universe results from the dynamics of a scalar field coupled to matter, suffer from the po…
Supersymmetron
Philippe Brax, Anne-Christine Davis
We consider a supersymmetric model of dark energy coupled to cold dark matter: the supersymmetron. In the absence of cold dark matter, the supersymmetron converges to a supersymmet…
Laboratory Tests of the Galileon
Philippe Brax, Clare Burrage, Anne-Christine Davis
The Galileon model is a ghost free scalar effective field theory containing higher derivative terms that are protected by the Galileon symmetry. The presence of a Vainshtein screen…
Strongly Coupled Chameleons and the Neutronic Quantum Bouncer
Philippe Brax, Guillaume Pignol
We consider the potential detection of chameleons using bouncing ultracold neutrons. We show that the presence of a chameleon field over a planar plate would alter the energy level…
