Momentum transfer models of interacting dark energy
Mark S. Linton, Robert Crittenden, Alkistis Pourtsidou
We consider two models of interacting dark energy, both of which interact only through momentum exchange. One is a phenomenological one-parameter extension to CDM, and the other…

Variable sound speed in interacting dark energy models
Mark S. Linton, Alkistis Pourtsidou, Robert Crittenden +1
We consider a self-consistent and physical approach to interacting dark energy models described by a Lagrangian, and identify a new class of models with variable dark energy sound…
