Thermodynamics of Spinor Quintom

Jing Wang, Shu-wang Cui, Cheng-min Zhang

摘要:

在旋量方案下讨论了含五原子物质的暗能量的热力学性质。(1)利用Cardy-Verlinde公式,研究了SpinorQuintom-B模型四个演化阶段中广义热力学第二定律成立的条件。我们还阐明了它与三个宇宙熵界的关系。(二)、我们考虑了Spinor Quintom DE与广义Chaubergin气体(GCG)理想流体组合的热力学稳定性,发现在$β>0$和$0<T<T_0$的情况下,我们所考虑的系统是热力学稳定的. (3)利用麦克斯韦关系和可积性条件,导出了所有热物理量作为熵或体积的函数,并给出了与量子微扰稳定性的关系。

英文摘要:

We discuss the thermodynamic properties of dark energy (DE) with Quintom matter in spinor scenario. (1).Using the Cardy-Verlinde formula, we investigate the conditions of validity of the Generalized Second Law of thermodynamics (GSL) in the four evolutionary phases of Spinor Quintom-B model. We also clarify its relation with three cosmological entropy bounds. (2). We take thermodynamic stability of the combination between Spinor Quintom DE and the generalized Chaplygin Gas (GCG) perfect fluid into account, and we find that in the case of $β>0$ and $0<T<T_0$, the system we consider is thermodynamically stable. (3) Making use of the Maxwell Relation and integrability condition, we derive all thermal quantities as functions of either entropy or volume, and present the relation with quantum perturbation stability.
