标题： On the oscillations of the inflaton field of the simplest $α$-attractor T-model

摘要： 在本工作中，我们考虑暴胀后的标量场的均匀振荡。 特别是，我们得到了最简单的$\alpha$-吸引子 T 模型中振荡标量场的（平均）状态方程的解析结果。 我们还研究了标量场衰变之前的暴胀后演化。 在标量场振荡期间，（平均）状态方程可能为宇宙学常数的状态方程。 这导致了振荡暴胀现象。 然而，我们证明了振荡暴胀的持续时间非常有限。 显示英文摘要

摘要： In this work, we consider homogeneous oscillations of the inflaton field after inflation. In particular, we obtain an analytical result for the (average) equation of state for the oscillating inflaton field for the simplest $\alpha$-attractor T-model. We also study the post-inflationary evolution before inflaton decay. It is possible that during inflaton field oscillation, the (average) equation of state is that of a cosmological constant. This leads to the phenomenon of oscillating inflation. However, we show that the duration of oscillating inflation is very limited.
