Einstein-Cartan理论中暴胀的Dirac场模型

Dirac-field model of inflation in Einstein-Cartan theory

Tomoki Watanabe

摘要:

本文在爱因斯坦-嘉当理论的框架内提出了一个具有平坦势的狄拉克场可以引起暴胀的宇宙学模型。它表明,我们的狄拉克场模型导致一个几乎尺度不变的密度波动谱由于自旋相互作用,自然产生的爱因斯坦-嘉当理论的场方程。

英文摘要:

We present a cosmological model in which a single Dirac field with a flat potential can give rise to inflation within the framework of the Einstein-Cartan theory. It is shown that our Dirac-field model leads to a nearly scale-invariant spectrum of density fluctuations owing to the spin-interaction which naturally arises from the field equations of the Einstein-Cartan theory.
