具有可变状态方程的理想流体宇宙的热力学

Thermodynamics of the Universe Filled with Perfect Fluid Having Variable Equation of State

Nairwita Mazumder, Subenoy Chakraborty

摘要:

研究了状态方程$p=ωρ,ω$为变量的理想流体宇宙的热力学。在这里,我们选择$ω$作为红移变量$z$的函数,并研究了$ω$的四种不同选择。此外,热力学的热力学定律检查考虑的视界(表观)作为一个物理系统的宇宙边界。

英文摘要:

We study the thermodynamics of the universe containing perfect fluid with equation of state $p=ωρ,ω$ is variable. Here we choose $ω$ to be a function of the red shift variable $z$ and four different choices of $ω$ has been investigated. Also the laws of thermodynamics are examined considering the universe bounded by the horizon (apparent) as a thermodynamical system.
