Exact Solutions to Non-Linear Symmetron Theory: One and Two Mirror Systems

Philippe Brax, Mario Pitschmann

We derive the exact analytical solutions to the symmetron field theory equations in the presence of a one or two mirror system. The one dimensional equations of motion are integrat…

Self-acceleration in scalar-bimetric theories

Philippe Brax, Patrick Valageas

We describe scalar-bimetric theories where the dynamics of the Universe are governed by two separate metrics, each with an Einstein-Hilbert term. In this setting, the baryonic and…

MICROSCOPE mission: first constraints on the violation of the weak equivalence principle by a light scalar dilaton

Joel Bergé, Philippe Brax, Gilles Métris +3

The existence of a light or massive scalar field with a coupling to matter weaker than gravitational strength is a possible source of violation of the weak equivalence principle. W…

Gravitational Waves in Doubly Coupled Bigravity

Philippe Brax, Anne-Christine Davis, Johannes Noller

We consider gravitational waves from the point of view of both their production and their propagation in doubly coupled bigravity in the metric formalism. In bigravity, the two gra…

Neutron Stars in Screened Modified Gravity: Chameleon vs Dilaton

Philippe Brax, Anne-Christine Davis, Rahul Jha

We consider the scalar field profile around relativistic compact objects such as neutron stars for a range of modified gravity models with screening mechanisms of the chameleon and…
