论文摘要
我们提出了Kaluza-Klein启发的Brans-Dicke重力模型，其中包含可能存在暗物质和暗能量。巨大的标量场和5维时空中的重力可以将其与Dilaton $ ϕ $，量规域$A_μ$以及标量塔塔$η_n$一起降低至4维重力。引入了两个额外的量规场，以形成“宇宙三合会”矢量场场景。然后，我们使用动态系统方法来分析关键点及其相应的物理参数。我们发现，在仅将kaluza-klein标量的零模式解耦的情况下，该系统既包含暗物质和暗能量阶段，具体取决于质量参数，并存在量规场的存在。
We propose the Kaluza-Klein inspired Brans-Dicke gravity model containing possible existence of dark matter and dark energy. The massive scalar field coupled with gravity in 5 dimensional spacetime can be reduced to 4 dimensional gravity along with the dilaton $ϕ$, gauge fields $A_μ$, and the tower of scalar fields $η_n$. Two additional gauge fields are introduced to form "Cosmic Triad" vector field scenario. We then use the dynamical system approach to analyze the critical points and their corresponding physical parameters. We found that in the case where only the zero mode of the Kaluza-Klein scalar is decoupled, the system contains both dark matter and dark energy phase depending on the mass parameter with the presence of the gauge field.
