An Introduction to Chameleon Gravity


Following work by Khoury and Weltman, we introduce a scalar field φ, the chameleon, which is conformally coupled to matter. That is, matter experiences a metric which is a conformal transform (parametrized by φ) of the Einstein metric. The effective potential of the field φ is a sum of its selfinteraction term and an exponential term due to the conformal… (More)
