量子宇宙幻影模型中物质主导阶段的优雅退出

A gracious exit from the matter-dominated phase in a quantum cosmic phantom model

Pedro F. Gonzalez-Diaz, Alberto Rozas-Fernandez

摘要:

来自普朗克的最新观测约束,当与其他宇宙学数据相结合时,为幻影场景提供了证据。在这项工作中,我们考虑了一个量子宇宙幻影模型中的物质粒子和标量场都与量子势,使有效质量与物质粒子的辐射相等时消失,导致在宇宙系统中的物质优势相,随后加速膨胀是允许的。

英文摘要:

The most recent observational constraints coming from Planck, when combined with other cosmological data, provide evidence for a phantom scenario. In this work we consider a quantum cosmic phantom model where both the matter particles and scalar field are associated with quantum potentials which make the effective mass associated with the matter particles to vanish at the time of matter-radiation equality, resulting in a cosmic system where a matter dominance phase followed by an accelerating expansion is allowed.
