Strongly Coupled Chameleon Fields: New Horizons in Scalar Field Theory

Abstract

We show that as a result of non-linear self-interactions, scalar field theories that couple to matter much more strongly than gravity are not only viable but could well be detected by a number of future experiments, provided these are properly designed to do so.
