Phase Space Dynamics of Non-Gravitational Interactions between Dark Matter and Dark Energy: The Case of Ghost Dark Energy

Ricardo Garcia-Salcedo, Tame Gonzalez, Israel Quiros

We study the phase space asymptotics of the so called Veneziano ghost dark energy models. Models where the ghost field's energy density: i) ${\rho }_{ghost}\propto H$, and ii) $ρ_{ghost}…
