具有非最小耦合五重物质的弯曲DGP膜上的弹跳宇宙
Bouncing universe with the non-minimally coupled quintom matter on the warped DGP Brane
摘要:
我们构造了一个五重态暗能量模型,其中包含两个非最小耦合的标量场,一个是quintessence场,另一个是phantom场,它们被限制在弯曲的DGP膜上。在此框架下,我们研究了一些重要的问题,如幻影分界线穿越,弹跳解的存在性和解的稳定性。我们表明,该模型占交叉的幻影分界线和实现的弹跳解决方案。该模型允许在$ω$ - $ω'$相平面的单独区域中的解的稳定性。
英文摘要:
We construct a quintom dark energy model with two non-minimally coupled scalar fields, one quintessence and the other phantom field, confined on the warped DGP brane. We study some important issues such as phantom divide line crossing, existence of the bouncing solutions and the stability of the solutions in this framework. We show that this model accounts for crossing of the phantom divide line and realization of the bouncing solutions. This model allows for stability of the solutions in separate regions of the $ω$-$ω'$ phase-plane.
