Releasing scalar fields: cosmological simulations of scalar-tensor theories for gravity beyond the static approximation.
Several extensions of general relativity and high energy physics include scalar fields as extra degrees of freedom. In the search for predictions in the nonlinear regime of cosmological evolution, the community makes use of numerical simulations in which the quasistatic limit is assumed when solving the equation of motion of the scalar field. In this Letter, we propose a method to solve the ful...
متن کاملGeneral Relativistic Radiant Shock Waves in the Post-Quasistatic Approximation
An evolution of radiant shock wave front is considered in the framework of a recently presented method to study self–gravitating relativistic spheres, whose rationale becomes intelligible and finds full justification within the context of a suitable definition of the post–quasistatic approximation. The spherical matter configuration is divided into two regions by the shock and each side of the ...
متن کاملScintillation in scalar-tensor theories of gravity
We study the scintillation produced by time-varying gravitational fields within scalar-tensor theories of gravity. The problem is treated in the geometrical optics approximation for a very distant light source emitting quasi plane monochromatic electromagnetic waves. We obtain a general formula giving the time dependence of the photon flux received by a freely falling observer. In the weak-fiel...
متن کاملWaveless Approximation Theories of Gravity
The analysis of a general multibody physical system governed by Einstein’s equations in quite difficult, even if numerical methods (on a computer) are used. Some of the difficulties – many coupled degrees of freedom, dynamic instability – are associated with the presence of gravitational waves. We have developed a number of “waveless approximation theories” (WAT) which repress the gravitational...
متن کاملRelativistic theories of interacting fields and fluids
We investigate divergence-type theories describing the disipative interaction betwen a field and a fluid. We look for theories which, under equilibrium conditions, reduce to the theory of a Klein-Gordon scalar field and a perfect fluid. We show that the requirements of causality and positivity of entropy production put non-trivial constraints to the structure of the interaction terms. These the...
