We show that, as a result of nonlinear self-interactions, it is feasible, at least in light of the bounds coming from terrestrial tests of gravity, measurements of the Casimir force and those constraints imposed by the physics of compact objects, big-bang nucleosynthesis and measurements of the cosmic microwave background, for there to exist, in our Universe, one or more scalar fields that couple to matter much more strongly than gravity does. These scalar fields behave like chameleons… 

Chameleon gravity, electrostatics, and kinematics in the outer galaxy

Light scalar fields are expected to arise in theories of high energy physics (such as string theory), and find phenomenological motivations in dark energy, dark matter, or neutrino physics. However,

Chameleon gravity, electrostatics, and kinematics in the outer galaxy

Light scalar fields are expected to arise in theories of high energy physics (such as string theory), and find phenomenological motivations in dark energy, dark matter, or neutrino physics. However,

Towards a UV completion of chameleons in string theory

Chameleons are scalar fields that couple directly to ordinary matter with gravitational strength, but which nevertheless evade the stringent constraints on tests of gravity because of properties they

COSMOLOGY OF CHAMELEONS WITH POWER-LAW COUPLINGS

In chameleon field theories, a scalar field can couple to matter with gravitational strength and still evade local gravity constraints due to a combination of self-interactions and the couplings to

Tests of chameleon gravity

The present state-of-the-art searches for screened scalars coupled to matter are summarized, and the current bounds on f(R) models that exhibit the chameleon mechanism are translated into a single parametrization to survey the state of the models.

No need for dark matter in galaxy clusters within Galileon theory

Modified gravity theories with a screening mechanism have acquired much interest recently in the quest for a viable alternative to General Relativity on cosmological scales, given their intrinsic

Disformal theories of gravity: from the solar system to cosmology

This paper is concerned with theories of gravity that contain a scalar coupled both conformally and disformally to matter through the metric. By systematically deriving the non-relativistic limit, it

Cosmological supersymmetric model of dark energy

Recently, a supersymmetric model of dark energy coupled to cold dark matter, the supersymmetron, has been proposed. In the absence of cold dark matter, the supersymmetron field converges to a

Environmental screening of dark matter haloes in f(R) gravity

In certain theories of modified gravity, solar system constraints on deviations from general relativity (GR) are satisfied by virtue of a so-called screening mechanism, which enables the theory to

Chameleon Cosmology

The evidence for the accelerated expansion of the Universe and the time dependence of the fine-structure constant suggests the existence of at least one scalar field with a mass of order H0. If such

Current acceleration from the dilaton and stringy cold dark matter

We argue that string theory has ingredients to provide us with candidates for cold dark matter and explain the current acceleration of our universe. In any generic string compactification the dilaton

The accelerating Universe and a limiting curvature proposal

We consider the hypothesis of a limiting minimal curvature in gravity as a way to construct a class of theories exhibiting late-time cosmic acceleration. Guided by the minimal curvature conjecture we

Violations of the equivalence principle in a dilaton-runaway scenario

We explore a version of the cosmological dilaton-fixing and decoupling mech- anism in which the dilaton-dependence of the low-energy effective action is extremized for infinitely large values of the

Detecting dark energy in orbit: The cosmological chameleon

We show that the chameleon scalar field can drive the current phase of cosmic acceleration for a large class of scalar potentials that are also consistent with local tests of gravity. These provide

We investigate the conditions under which cosmological variations in physical 'constants' and scalar fields are detectable on the surface of local gravitationally bound systems, such as planets, in

It is argued that a number of models in which the energy density of the scalar field red-shifts in a specific manner are studied could reconcile the low dynamical estimates of the mean mass density with the negligibly small spatial curvature preferred by inflation.
