论文摘要
在本文中，我们以两种形式使用Tsallis全息暗能模型，以相互作用和非相互作用的情况来获取某些参数作为FRW宇宙中Tsallis模型的能量密度的状态方程，以涉及Quintessence模型的复杂形式。我们将通过改善潜力并研究标量场动力学来研究复杂精髓的宇宙学。然后，我们在两种情况下分析（$ω-ω'$）和稳定性，即非相互作用和相互作用。我们将通过计算分数能量密度$ω__{d} $来探讨这些情况是否描述了真实的宇宙，并通过考虑该字段的实际部分是慢速滚动字段来探讨典型场效应的两个部分（复杂和实际部分）。我们知道，分数能量密度（$ω_{d}> 1 $）的部分没有描述真实的宇宙。另外，我们指定了一个相互作用的耦合参数$ b^{2} $，该$取决于tsallis全息模型（$δ$）相对于分数能量密度（$ 0.73 $）的常数参数。与实际典型模型中的分数能量密度和相互作用耦合之间的独立性不同，我们确定了这些理论中这些参数之间的关系。最后，通过绘制一些数字，我们在两种情况下指定了（$ω-ω'$）和（$ν_{s}^{2} $）的功能，并将结果彼此比较。
In this paper, we use a Tsallis holographic dark energy model in two forms, interacting and non-interacting cases, to acquire some parameters as the equation of state for the energy density of the Tsallis model in the FRW universe concerning the complex form of quintessence model. We will study the cosmology of complex quintessence by revamping the potential and investigating the scalar field dynamics. Then we analyze ($ω-ω'$) and stability in two cases, i.e., non-interacting and interacting. We will explore whether these cases describe a real universe by calculating fractional energy density $Ω_{D}$ and concerning two parts of the quintessence field effect ( complex and real part ) by considering the real part of this field to be a slow-roll field. We know that the part in which the fractional energy density ($Ω_{D} > 1$) does not describe a real universe. Also, we specified an interacting coupling parameter $b^{2}$ that depends on the constant parameter of the Tsallis holographic model ($δ$) with respect to fractional energy density ($0.73$). Unlike independence between the fractional energy density and interacting coupling in the real quintessence model, we determine a relationship among these parameters in this theory. Finally, by plotting some figures, we specify the features of ($ω-ω'$) and ($ν_{s}^{2}$) in two cases and compare the result with each other.
