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.
In this paper, we explore various cosmological parameters and cosmological planes ($ω_D-{ω_D}^{\prime}$, statefinder) for new Tsallis agegraphic dark energy in the framework of Chern-Simons modified gravity. We consider this scenario in a flat FRW universe for both non-interacting and interacting cases, between dark energy and dark matter. It is observed that the equation of state parameter gives quintessence-like nature of the universe in all of the cases. Also, the squared of the sound speed shows unstable behaviour for this scenario. The $ω_D-{ω_D}^{\prime}$ plane represents the freezing re…
We investigate alternative candidates to dark energy that can explain the current state of the universe in the framework of the generalized teleparallel theory of gravity $f(T)$ where $T$ denotes the torsion scalar. To achieve this, we carried out a series of reconstruction taking into account to the ordinary and entropy-corrected versions of the holographic and new agegraphic dark energy models. These models used as alternative to dark energy in the literature in order describe the current state of our universe. It is remarked that the models reconstructed indicates behaviors like phantom or …
Thermodynamics of interacting entropy-corrected holographic dark energy in a non-flat FRW universe
在圈量子宇宙学的框架下,通过对熵-面积关系的量子修正,提出了一种所谓的“熵修正全息暗能量“(ECHDE)来解释暗能量主导的宇宙.利用这一新定义,我们研究了它的物理特性,包括熵和能量守恒。我们描述了非平坦宇宙中ECHDE与暗物质相互作用的物理解释。得到了暗分量的相互作用项与热涨落之间的关系。我们的研究进一步推广了早期的作品[M. R. Setare和E.C. Vagenas,Phys. Lett. B 666(2008)111; B. Wang等人,Phys. Lett. #20062;,在这个方向?
