关于暗能量的化学势
On the Chemical Potential of Dark Energy
摘要：
人们普遍认为，由于一种称为暗能量的新流体成分的存在，所观测到的宇宙正在加速。在这篇文章中，非零化学势的热力学后果的暗能量组件进行了讨论，特别强调幻影流体的情况下。研究发现，如果暗能量流体具有负的化学势，则幻影场假设与文献中最近提出的不需要负温度的假设在理论上是一致的。
英文摘要：
It is widely assumed that the observed universe is accelerating due to the existence of a new fluid component called dark energy. In this article, the thermodynamics consequences of a nonzero chemical potential on the dark energy component is discussed with special emphasis to the phantom fluid case. It is found that if the dark energy fluid is endowed with a negative chemical potential, the phantom field hypothesis becomes thermodynamically consistent with no need of negative temperatures as recently assumed in the literature.
