暗能量与暗物质相互作用,

Dark energy interacting with dark matter and unparticle

Songbai Chen, Jiliang Jing

摘要:

研究了标准平坦FRW宇宙学中暗能量与暗物质和非粒子相互作用模型的动力学行为。我们考虑了四种不同的相互作用模型,并研究了临界点的稳定性。我们发现,存在晚时间标度吸引子对应于一个加速的宇宙和缓解的重合问题取决于模型中的参数的选择。

英文摘要:

We study dynamical behaviors of the dark energy models interacting with dark matter and unparticle in the standard flat FRW cosmology. We considered four different interacting models and examined the stability of the critical points. We find that there exist late-time scaling attractors corresponding to an accelerating Universe and the alleviation of the coincidence problem depends on the choice of parameters in the models.
