A new class of “dark energy” models is reviewed and developed, in which the relativistic theory of solids is used to construct material models of dark energy. These are models which include the effects of a continuous medium with well defined physica... Read More about Material models of dark energy.

Simple implementation of general dark energy models (2014)
Journal Article
Bloomfield, J. K., & Pearson, J. A. (2014). Simple implementation of general dark energy models. Journal of Cosmology and Astroparticle Physics, 2014, Article 17. https://doi.org/10.1088/1475-7516/2014/03/017

We present a formalism for the numerical implementation of general theories of dark energy, combining the computational simplicity of the equation of state for perturbations approach with the generality of the effective field theory approach. An effe... Read More about Simple implementation of general dark energy models.

Computing model independent perturbations in dark energy and modified gravity (2014)
Journal Article
Battye, R. A., & Pearson, J. A. (2014). Computing model independent perturbations in dark energy and modified gravity. Journal of Cosmology and Astroparticle Physics, 2014(03), Article 051. https://doi.org/10.1088/1475-7516/2014/03/051

We present a methodology for computing model independent perturbations in dark energy and modified gravity. This is done from the Lagrangian for perturbations, by showing how field content, symmetries, and physical principles are often sufficient ing...
