Dynamics of interacting quintessence

الأصل · EN

In this paper, we investigate coupled quintessence with scaling potential assuming specific forms of the coupling as A namely, αρₘ, βρϕ and σ(ρₘ+ρϕ), and present phase space analysis for three different interacting models. We focus on the attractor solutions that can give rise to late time acceleration with ΩDE/ΩDM of order unity in order to alleviate the coincidence problem.
