摘要:

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?

英文摘要:

A so-called "entropy-corrected holographic dark energy" (ECHDE), was recently proposed to explain the dark energy-dominated universe with the help of quantum corrections to the entropy-area relation in the setup of loop quantum cosmology. Using this new definition, we investigate its thermodynamical features including entropy and energy conservation. We describe the thermodynamical interpretation of the interaction between ECHDE and dark matter in a non-flat universe. We obtain a relation between the interaction term of the dark components and thermal fluctuation. Our study further generalizes the earlier works [M.R. Setare and E.C. Vagenas, Phys. Lett. B 666 (2008) 111; B. Wang et al., Phys. Lett. B 662 (2008) 1] in this direction.
