Scalar perturbation and stability of Ricci dark energy
发表期刊PHYSICS LETTERS B
关键词Infrared Cutoff Cosmology Models Bulk Gas
摘要The Ricci dark energy (RDE) proposed to explain the accelerating expansion of the universe requires its parameter alpha < 1, whose value will determine the behavior of RDE. In this Letter, we study the scalar perturbation of RDE with and without matter in the universe, and we find that in both cases, the perturbation is stable if alpha > 1/3, which gives a lower bound for alpha theoretically.
