非平坦宇宙中相互作用熵修正的新年龄暗能量

Interacting entropy-corrected new agegraphic dark energy in non-flat universe

K. Karami, A. Sorouri

摘要:

在这里,我们考虑在非平坦的FRW宇宙中的新年龄暗能量模型的熵校正版本。我们推导出精确的微分方程,它决定了熵校正后的新年龄暗能量密度参数在与暗物质相互作用下的演化。我们还得到了状态方程和减速参数,并提出了一个必要条件,选定的模型跨越幻影鸿沟。此外,我们根据相互作用熵修正的新年龄模型的演化行为重建了幻影标量场的势和动力学。

英文摘要:

Here we consider the entropy-corrected version of the new agegraphic dark energy model in the non-flat FRW universe. We derive the exact differential equation that determines the evolution of the entropy-corrected new agegraphic dark energy density parameter in the presence of interaction with dark matter. We also obtain the equation of state and deceleration parameters and present a necessary condition for the selected model to cross the phantom divide. Moreover, we reconstruct the potential and the dynamics of the phantom scalar field according to the evolutionary behavior of the interacting entropy-corrected new agegraphic model.
