Models of dark matter coupled to dark energy
Pourtsidou, A.; Skordis, C.; Copeland, E. J. (2013)We present three distinct types of models of dark energy in the form of a scalar field which is explicitly coupled to dark matter. Our construction draws from the pull-back formalism for fluids and generalizes the fluid ...

Parametrized post-Friedmannian framework for interacting dark energy theories
Skordis, C.; Pourtsidou, A.; Copeland, E. J. (2015)We present the most general parametrization of models of dark energy in the form of a scalar field which is explicitly coupled to dark matter. We follow and extend the parametrized post-Friedmannian approach, previously ...
