# Constraining Lorentz violation with cosmology.

@article{Zuntz2008ConstrainingLV, title={Constraining Lorentz violation with cosmology.}, author={J. Zuntz and P. Ferreira and T. Zlosnik}, journal={Physical review letters}, year={2008}, volume={101 26}, pages={ 261102 } }

The Einstein-aether theory provides a simple, dynamical mechanism for breaking Lorentz invariance. It does so within a generally covariant context and may emerge from quantum effects in more fundamental theories. The theory leads to a preferred frame and can have distinct experimental signatures. In this Letter, we perform a comprehensive study of the cosmological effects of the Einstein-aether theory and use observational data to constrain it. Allied to previously determined consistency and… Expand

Anisotropic Einstein-aether cosmological models

- Physics

We investigate a class of spatially anisotropic cosmological models in Einstein-aether theory with a scalar field in which the self-interaction potential depends on the timelike aether vector field… Expand

Cosmological constraints on Lorentz violating dark energy

- Physics
- 2013

The role of Lorentz invariance as a fundamental symmetry of nature has been lately reconsidered in different approaches to quantum gravity. It is thus natural to study whether other puzzles of… Expand

Cosmological constraints on deviations from Lorentz invariance in gravity and dark matter

- Physics
- 2014

We consider a scenario where local Lorentz invariance is violated by the existence of a preferred time direction at every space-time point. This scenario can arise in the context of quantum gravity… Expand

Coupling the inflaton to an expanding aether

- Physics
- 2010

We consider a Lorentz-violating theory of inflation consisting of Einstein-aether theory with a scalar inflaton coupled bilinearly to the expansion of the aether. We determine the conditions for… Expand

We consider a cosmological setup with the inflaton field in the presence of a redshift dependent Lorentz-violating time-like background to address the inflationary regime and other phases of the… Expand

Cosmological Perturbations in Einstein-Aether Theories

- Physics
- 2011

In this thesis we study the Einstein-Aether (E-A) theory from the point of view of its cosmological perturbations. We are interested in the constraints that may be obtained from this analysis and the… Expand

Cosmologies in Horndeski’s second-order vector-tensor theory

- Physics
- 2013

A bstractHorndeski derived a most general vector-tensor theory in which the vector field respects the gauge symmetry and the resulting dynamical equations are of second order. The action contains… Expand

Primordial perturbations in Einstein-aether and BPSH theories

- Physics

We study the primordial perturbations generated during a stage of single-field inflation in Einstein-aether theories. Quantum fluctuations of the inflaton and aether fields seed long wavelength… Expand

Hořava Gravity in the Effective Field Theory formalism: From cosmology to observational constraints

- Physics

Abstract We consider Hořava gravity within the framework of the effective field theory (EFT) of dark energy and modified gravity. We work out a complete mapping of the theory into the EFT language… Expand

Testing general relativity with present and future astrophysical observations
