暗旋量驱动暴胀

Dark spinor driven inflation

S. Shankaranarayanan

摘要:

暴胀被认为是描述早期宇宙的最佳范式。然而,目前还不清楚推动通货膨胀的领域的性质是什么。在这个演讲中,我们讨论了旋量场驱动暴胀的可能性。旋胀子--暗旋量场的标量凝聚体--具有单个标量自由度,并导致与标量场相同的加速度方程。我们还讨论了这个模型的优势相比,标量场驱动的通货膨胀,并讨论其观测的相关性。

英文摘要:

Inflation is considered to be the best paradigm for describing the early universe. However, it is still unclear what is the nature of the field which drives inflation. In this talk, we discuss the possibility of spinor field driving inflation. Spinflaton -- a scalar condensate of the dark spinor field -- has a single scalar degree of freedom and leads to the identical acceleration equation as the scalar field. We also discuss the advantages of this model compared to the scalar field driven inflation and discuss its observational relevance.
