具有变化（负绝对）温度的理想气体：暗能量的替代物？
Ideal gas with a varying (negative absolute) temperature: An alternative to dark energy?
摘要：
目前的工作是一个尝试，以调查是否可以通过假设宇宙流体是一个理想气体与特定的气体常数，但变化的负绝对温度（NAT）的宇宙从膨胀抵消的演化历史。这项工作的动机是寻找一种替代“异国情调”和“超自然”的暗能量（DE）。事实上，NAT作为一个“有效的精华”工作，既不需要处理像DE这样的奇异物质，也不需要处理修改的引力理论。为了完整起见，我们在本文的第3节中发布了一些关于NAT的说明。
英文摘要：
The present work is an attempt to investigate whether the evolutionary history of the Universe from the offset of inflation can be described by assuming the cosmic fluid to be an ideal gas with a specific gas constant but a varying negative absolute temperature (NAT). The motivation of this work is to search for an alternative to the "exotic" and "supernatural" dark energy (DE). In fact, the NAT works as an "effective quintessence" and there is need to deal neither with exotic matter like DE nor with modified gravity theories. For the sake of completeness, we release some clarifications on NATs in Section 3 of the paper.
