QCD鬼f(G)引力中的广义热力学第二定律

Generalized second law of thermodynamics in QCD ghost f(G) gravity

Surajit Chattopadhyay

摘要:

考虑到平坦FRW宇宙中尺度因子的幂律性,我们提出了一种基于QCD鬼暗能量的$f(G)$引力重建方案.我们重构了有效状态方程参数,观察到了状态方程参数的“精华”行为。此外,将动力学视视界看作宇宙的包络视界,我们观察到广义热力学第二定律对重建的$f(G)$引力是成立的。

英文摘要:

Considering power-law for of scale factor in a flat FRW universe we reported a reconstruction scheme for $f(G)$ gravity based on QCD ghost dark energy. We reconstructed the effective equation of state parameter and observed "quintessence" behavior of the equation of state parameter. Furthermore, considering dynamical apparent horizon as the enveloping horizon of the universe we have observed that the generalized second law of thermodynamics is valid for this reconstructed $f(G)$ gravity.
