标题： Thermodynamics of viscous dark energy in an RSII braneworld

摘要： 我们证明，对于充满相互作用粘性暗能量和暗物质的RSII膜宇宙，总是可以将弗里德曼方程改写为表观视界处的热力学第一定律，$dE=T_hdS_h+WdV$。 此外，无论5维动态牛顿常数$G_5$是常数还是随时间变化，在膜上由表观视界包围的区域内，广义热力学第二定律都可以得到满足。 这些结果与暗能量的具体形式无关。 我们的研究进一步支持，在具有空间曲率的加速宇宙中，从热力学角度来看，表观视界是一个物理边界。 显示英文摘要

摘要： We show that for an RSII braneworld filled with interacting viscous dark energy and dark matter, one can always rewrite the Friedmann equation in the form of the first law of thermodynamics, $dE=T_hdS_h+WdV$, at apparent horizon. In addition, the generalized second law of thermodynamics can fulfilled in a region enclosed by the apparent horizon on the brane for both constant and time variable 5-dynamical Newton's constant $G_5$. These results hold regardless of the specific form of the dark energy. Our study further support that in an accelerating universe with spatial curvature, the apparent horizon is a physical boundary from the thermodynamical point of view.
