幂律熵修正的Ricci暗能量与标量场动力学
Power-Law Entropy Corrected Ricci Dark Energy and Dynamics of Scalar Fields
摘要：
受全息原理的启发，有人提出，暗能量（DE）密度可以与宇宙事件视界的面积$A$成反比。然而，这种模型会有一个连续性问题。本文研究了非平坦Friedmann-Robertson-Walker宇宙中的幂律熵修正全息DE（PLECHDE）模型，其中未来事件视界被Ricci标量曲率的平均半径所代替.推导了在存在DE与暗物质（DM）相互作用时的状态方程参数$ω_Λ$、减速参数$q$和能量密度参数$Ω_D'$的演化。我们考虑了Ricci-PLECHDE模型和修正的Chaubergin气体（MCG）以及快子、K-本质、介子和精粹标量场之间的对应关系。根据相互作用熵修正全息DE模型的演化行为，重建了标量场模型的势场和动力学。
英文摘要：
Motivated by the holographic principle, it has been suggested that the Dark Energy (DE) density can be inversely proportional to the area $A$ of the event horizon of the universe. However, this kind of model would have a casuality problem. In this work, we study the power-law entropy corrected holographic DE (PLECHDE) model in the non-flat Friedmann-Robertson-Walker universe, with the future event horizon replaced by the average radius of the Ricci scalar curvature. We derive the equation of state parameter $ω_Λ$, the deceleration parameter $q$ and the evolution of energy density parameter $Ω_D'$ in presence of interaction between DE and Dark Matter (DM). We consider the correspondence between our Ricci-PLECHDE model and the Modified Chaplygin Gas (MCG) and the tachyon, K-essence, dilaton and quintessence scalar fields. The potential and the dynamics of the scalar field models have been reconstructed according to the evolutionary behaviour of the interacting entropy-corrected holographic DE model.
