Reconstruction process of scalar field models (quintessence, tachyon, dilaton and K-essence), which can be performed by making use of some dark energy density definitions such as holographic, Ricci, new agegraphic and ghost types proposals, has been an interesting and very attractive area to many physicists in literature. In this work, in a five-dimensional framework, we establish a correspondence between the quintessence, tachyon and the dilaton type scalar field definitions and the generalized ghost dark energy model by considering the extended form of the Kaluza–Klein (EKK) gravity. Accordingly, we numerically study the associated equation of state parameters, as well as their kinetic energy and scalar potential terms.

从扩展的Kaluza–Klein角度看的Ghost标量场暗能量模型

标量场模型(典型,tachyon,dilaton和K-essence)的重建过程可以通过使用一些暗能量密度定义(例如全息图,Ricci,新的年龄和幽灵类型建议)来执行,这是一个有趣且非常重要的过程。对许多物理学家来说是一个吸引人的领域。在这项工作中,我们在一个五维框架中,通过考虑Kaluza-Klein(EKK)引力的扩展形式,建立了精粹,tachyon和dilaton型标量场定义与广义鬼暗能量模型之间的对应关系。因此,我们对状态参数的关联方程及其动能和标量势项进行了数值研究。
