宇宙二元性和旋量Quintom的状态发现者诊断

Cosmic Duality and Statefinder Diagnosis of Spinor Quintom

Jing Wang, Tian Lan, Tong-Jie Zhang

摘要:

本文利用对偶性研究了不同的Spinor Quintom暗能量(DE)模型之间可能存在的联系。然后,我们将状态发现诊断应用于这些模型。通过这个诊断对{ $\{r,s\}$ },我们以一种模型独立的方式将一个Quintom DE模型与其他模型区分开来。一类这些Spinor Quintom模型的演化轨迹的状态发现参数平面。我们还得到了参数$r$和$s$的当前位置,这些位置在理论上对应于不同的模型在statefinder参数平面。

英文摘要:

In this paper, we study the possible connections among different Spinor Quintom Dark Energy (DE) models by the aid of duality. Then we apply the statefinder diagnostic to these models. By this diagnostic pair {$\{r,s\}$}, we differentiate one Quintom DE model from the others in a model independent manner. A class of evolutionary trajectories of these Spinor Quintom models are presented in the statefinder parameter planes. We also obtain the current locations of the parameters $r$ and $s$, and these locations correspond to different models in statefinder parameter planes theoretically.
