Scale Invariance from Spontaneous Breaking of Conformal Symmetry
Speaker(s): Justin Khoury
Abstract: I will discuss a novel framework of the very early universe which addresses the traditional horizon and flatness problems of big bang cosmology and predicts a scale invariant spectrum of perturbations. Unlike inflation, this scenario requires no exponential superluminal expansion of space-time... read more

Chameleon Scalar Fields: Detecting Dark Energy with Tests of Gravity
Speaker(s): Justin Khoury
Abstract: Chameleon scalar fields are candidates for the dark energy, the mysterious component causing the observed acceleration of the universe. Their defining property is a mass which depends on the local matter density: they are massive on Earth, where the density is high, but essentially massless in the c... read more
