论文摘要
在本文中，我们认为可以仅通过具有bose-Einstein凝结物样势（称为CSFDE）的复杂标量场来描述暗能量，即具有自我交互和质量项。特别是，我们分析了一种解决方案，该解决方案在后期的快速振荡方案中表现为宇宙常数。我们的建议充分描述了标准均匀和平坦的弗里德曼动力学，此外，在这种典范中 - 复杂的标量场景，可以模仿与暗能量相关的动力学。但是，当在此景观中实施精度宇宙学测试时，该模型在A_I的有限型制度中得出的通用状态方程（这对应于标量场打开的规模因素），因此不能受到后期当前观察值的限制，因为分析限制仅由分析限制在值中由值划分的标准参数由该值划分的模型。这个结果是一个明确的提示，可以考虑使用两个标量字段的未来CSFDE模型，以研究宇宙的早期动态。
In this paper we consider that dark energy could be described solely by a complex scalar field with a Bose-Einstein condensate-like potential (denoted as CSFDE), that is, with a self-interaction and a mass term. In particular, we analyse a solution which in a fast oscillation regime at late-times behaves as a Cosmological Constant. Our proposal adequately describes the standard homogeneous and flat Fridman dynamics, furthermore, in this quintessence--complex scalar field scenario it is possible to mimic the dynamics related to dark energy. However, when the precision cosmological tests are implemented in this landscape, the generic Equation-of-State derived for this model in a restricted regime of a_i (which corresponds to the scale factor at which the scalar field turns on), cannot be constrained by late-time current observations, since the analysis constraints solely the scalar field parameters within values ruled out by the theoretical model. This result is a clear hint to consider future CSFDE models with, for instance, two scalar fields in order to study the early-time dynamics of the Universe.
