暗能量与暗物质和辐射相互作用的热力学

Thermodynamics of dark energy interacting with dark matter and radiation

Mubasher Jamil, Emmanuel N. Saridakis, M. R. Setare

摘要:

我们研究了广义热力学第二定律在宇宙学场景中的有效性,其中暗能量与暗物质和辐射相互作用。分别计算每个流体组分和表观视界本身的熵变,我们表明,广义第二定律总是普遍有效的,独立于特定的相互作用形式,流体状态方程参数和背景几何。

英文摘要:

We investigate the validity of the generalized second law of thermodynamics, in the cosmological scenario where dark energy interacts with both dark matter and radiation. Calculating separately the entropy variation for each fluid component and for the apparent horizon itself, we show that the generalized second law is always and generally valid, independently of the specific interaction form, of the fluids equation-of-state parameters and of the background geometry.
