非定域引力理论的暴胀

Inflation from a Non-Local Theory of Gravity

Philip Stephens

摘要:

本文研究了非定域引力理论的暴胀动力学。这一理论基于爱因斯坦-希尔伯特作用量中的里奇标量的导数,以前被发现是没有幽灵的,并产生了一种跳跃的宇宙学。微扰谱的计算和发现是类似的混沌膨胀。

英文摘要:

This paper studies the inflationary dynamics of a Non-Local Theory of gravity. This theory, based around derivatives of the Ricci Scalar in the Einstein-Hilbert action, was previously found to be Ghost free, and to give rise to a bouncing cosmology. Perturbation spectra are calculated and found to be similar to those for chaotic inflation.
