论文摘要
我们提出了一个新的统一模型，该模型在$ f（r，ϕ）$重力的背景下使用五个维度的大型标量场进行了描述。标量场在围绕Branworld模型中的3-大国的大部分中进行了考虑。我们表明，对于$％f（r，ϕ）$函数的特定选择，我们可以描述4维时时间的爱因斯坦重力。我们获得了宇宙膨胀速度与批量扩展速度之间的关系。我们还建议暗物质由标量场质量代表，而暗能量是该场的动能。最后，我们表明，根据条件，人们可以获得暗物质密度\的百分比和普通物质的密度。
We propose a new unified model that describes~dark energy and dark matter in the context of $f(R,ϕ)$ gravity using a massive scalar field in five dimensions. The scalar field is considered in the bulk that surrounds the 3-brane in branworld model. We show that for a specific choice of the $% f(R,ϕ)$ function, we can describe the Einstein gravitation in 4-dimensional space-time. We obtain a relationship between the speed of the universe's expansion and the speed of the bulk's expansion. We also propose that the dark matter is represented by the scalar field mass and that the dark energy is a kinetic energy of this field. Finally, we show that, according to conditions, one can obtain the percentages of density\ of dark matter and the density of ordinary matter.
