幂律熵修正的Hoenava-Lifshitz宇宙学中的新图解暗能量
Power Law Entropy Corrected New-Agegraphic Dark Energy in Hořava-Lifshitz Cosmology
摘要:
在Hoenava-Lifshitz宇宙学框架下研究了具有幂律修正熵的新年龄暗能量(NADE)模型.对于含有暗物质和幂律熵修正NADE(PLECNADE)相互作用的非平坦宇宙,我们得到了密度参数和减速参数演化的微分方程.为了研究参数行为,我们使用了一种有趣的状态参数形式作为红移的函数$ω_Λ(z)=ω_0+ω_1 z$。我们发现当耦合参数为非零时,态参数会发生幻影穿越,从而支持了相互作用的暗能量模型。
英文摘要:
We investigate the new agegraphic dark energy (NADE) model with power-law corrected entropy in the framework of Hořava-Lifshitz cosmology. For a non-flat universe containing the interacting power-law entropy-corrected NADE (PLECNADE) with dark matter, we obtain the differential equation of the evolution of density parameter as well as the deceleration parameter. To study parametric behavior, we used an interesting form of state parameter as function of redshift $ω_Λ(z)=ω_0+ω_1 z$. We found that phantom crossing occurs for the state parameter for a non-zero coupling parameter, thus supporting interacting dark energy model.
