论文摘要
我们表明，扩展的宇宙学方程式从最近应用于恒星建模的状态开始开发的是一种与标准标量电势一致的可行的深色能量模型。此外，我们发现基于具有适当自我交互潜力的规范标量场的拉格朗日公式。最后，我们符合文献中研究良好的混凝土函数获得的标量势。我们的结果可能是建模者和粒子物理学家的兴趣。
We show that the extended cosmological equation-of-state developed starting from a Chaplygin equation-of-state, recently applied to stellar modeling, is a viable dark energy model consistent with standard scalar potentials. Moreover we find a Lagrangian formulation based on a canonical scalar field with the appropriate self-interaction potential. Finally, we fit the scalar potential obtained numerically with concrete functions well studied in the literature. Our results may be of interest to model builders and particle physicists.
