论文摘要
在这项工作中，我们研究了使用近似的相位积分方法到三阶的相位积分方法的标量功率谱和光谱指数。我们表明，半经典方法以良好的精度重现了Starobinsky模型的标量功率谱，并且光谱指数的值与观测值有利。另外，我们将结果与均匀近似方法和二阶慢滚近似进行比较。
In this work we study the scalar power spectrum and the spectral index for the Starobinsky inflationary model using the phase integral method up-to third-order of approximation. We show that the semiclassical methods reproduce the scalar power spectrum for the Starobinsky model with a good accuracy, and the value of the spectral index compares favorably with observations. Also, we compare the results with the uniform approximation method and the second-order slow-roll approximation.
