相互作用暗能量模型中的不动点

Fixed points in interacting dark energy models

Xi-ming Chen, Yungui Gong

摘要:

研究了两个相互作用的暗能量模型的动力学行为。除了在指数势的非相互作用quintessence模型中发现的标度吸引子之外,在相互作用暗能量模型中也发现了新的加速标度吸引子。符合问题被简化为相互作用的暗能量模型中参数的选择。

英文摘要:

The dynamical behaviors of two interacting dark energy models are considered. In addition to the scaling attractors found in the non-interacting quintessence model with exponential potential, new accelerated scaling attractors are also found in the interacting dark energy models. The coincidence problem is reduced to the choice of parameters in the interacting dark energy models.
