论文摘要
我们在本文中研究了深色能源的多场模型。我们认为，我们考虑的一个多个标量场是一个多场tachyon，而另一个是多场幻影量标量表。我们通过考虑适合这些模型的平方电位来对系统空间中的系统进行分析。通过开发自主动力学系统，进行临界点及其稳定性分析。已经观察到，这些稳定的关键要点得到了权力法解决方案的满足。继续进行分析，我们可以预测宇宙的命运。该模型的一个特殊特征是，它影响状态参数W的方程，从而改变了它在宇宙的进化阶段比负的方程更大。因此，它的全部是关于幻影鸿沟，在这些模型中，宇宙的演变中证明是决定性的。
We investigate a multi-field model of dark energy in this paper. We develop a model of dark energy with two multiple scalar fields, one we consider, is a multifield tachyon and the other is multi-field phantom tachyon scalars. We make an analysis of the system in phase space by considering inverse square potentials suitable for these models. Through the development of an autonomous dynamical system, the critical points and their stability analysis is performed. It has been observed that these stable critical points are satisfied by power law solutions. Moving on towards the analysis we can predict the fate of the universe. A special feature of this model is that it affects the equation of state parameter w to alter from being it greater than negative one to be less than it during the evolutionary phase of the universe. Thus, its all about the phantom divide which turns out to be decisive in the evolution of the cosmos in these models.
