相互作用暗能量在事件视界上的广义热力学第二定律

Generalized Second Law of Thermodynamics on the Event Horizon for Interacting Dark Energy

Nairwita Mazumder, Subenoy Chakraborty

摘要:

在这里,我们试图找到的广义热力学第二定律(GRESS)的有效性的条件,假设热力学第一定律的事件视界在这两种情况下,当FRW宇宙充满相互作用的两个流体系统-一个在冷暗物质的形式,另一个是全息暗能量或新时代的图形暗能量。利用最近的观测数据,我们发现,对于新时代的图形模型,Gynn在精粹时代和幻影时代都成立,而对于全息暗能量,Gynn只在幻影时代成立。

英文摘要:

Here we are trying to find the conditions for the validity of the generalized second law of thermodynamics (GSLT) assuming the first law of thermodynamics on the event horizon in both cases when the FRW universe is filled with interacting two fluid system- one in the form of cold dark matter and the other is either holographic dark energy or new age graphic dark energy. Using the recent observational data we have found that GSLT holds both in quintessence era as well as in phantom era for new age graphic model while for holographic dark energy GSLT is valid only in phantom era.
