Chameleon scalar fields in relativistic gravitational backgrounds

Chameleon scalar fields in relativistic gravitational backgrounds

We study the field profile of a scalar field $\phi$ that couples to a matter fluid (dubbed a chameleon field) in the relativistic gravitational background of a spherically symmetric spacetime. Employing a linear expansion in terms of the gravitational potential $\Phi_c$ at the surface of a compact object with a …
