修正的Chaubergin气体热力学与超快离子场
Thermodynamics of Modified Chaplygin Gas and Tachyonic Field
摘要：
本文推广了文献[10]在修正的Chaubergin气体模型和快子场模型中的结果。在这里，我们研究了两种模型的体积和温度的热力学行为和状态方程。我们把我们以前工作[12]的解和相应的状态方程用于快子场模型。我们还用热状态方程研究了快子场模型的热力学稳定性，证明了在热力学膨胀过程中不存在临界点。本文在假定一些初始条件的情况下，讨论了由快子场的膨胀引起的$T_{*}$的确定问题。在这里，热量已使用一些减少的参数进行了研究。
英文摘要：
Here we generalize the results of the work of ref. [10] in modified Chaplygin gas model and tachyonic field model. Here we have studied the thermodynamical behaviour and the equation of state in terms of volume and temperature for both models. We have used the solution and the corresponding equation of state of our previous work [12] for tachyonic field model. We have also studied the thermodynamical stability using thermal equation of state for the tachyonic field model and have shown that there is no critical points during thermodynamical expansion. The determination of $T_{*}$ due to expansion for the tachyonic field have been discussed by assuming some initial conditions. Here, the thermal quantities have been investigated using some reduced parameters.
