关于负温体模热力学

On phantom thermodynamics with negative temperature

Yun Soo Myung

摘要:

讨论了含有$ω=p/ρ<-1/3$标记暗能量流体的Friedmann-Robertson-Walker宇宙的热力学性质.利用可积性条件,我们证明了即使温度为负值,$w<-1$的幻影相仍然是热力学允许的,因为在这种情况下,至少存在一个保持$p$和$ρ$物理值不变的条件

英文摘要:

We discuss the thermodynamic properties of the Friedmann-Robertson-Walker universe with dark energy fluids labelled by $ω=p/ρ<-1/3$. Using the integrability condition, we show that the phantom phase of $w<-1$ can still be thermodynamically allowed even when the temperature takes on negative values because in that case, there exists at least a condition of keeping physical values for $p$ and $ρ$
