相互作用全息暗能量模型的热力学图像

Thermodynamical picture of the interacting holographic dark energy model

M R Setare

摘要:

本文对非平坦宇宙中的全息暗能量模型给出了一个理论解释。对于这种情况,特征长度不再是事件视界的半径($R_E$),而是从视界球面测量的事件视界半径($L$)。此外,当非平坦宇宙中全息暗能量模型的暗分量之间存在相互作用时,其物理解释会因稳定的热涨落而改变。得到了暗分量的相互作用项与这种热涨落之间的关系。

英文摘要:

In the present paper, we provide a thermodynamical interpretation for the holographic dark energy model in a non-flat universe. For this case, the characteristic length is no more the radius of the event horizon ($R_E$) but the event horizon radius as measured from the sphere of the horizon ($L$). Furthermore, when interaction between the dark components of the holographic dark energy model in the non-flat universe is present its thermodynamical interpretation changes by a stable thermal fluctuation. A relation between the interaction term of the dark components and this thermal fluctuation is obtained.
