论文摘要
在这项工作中，我们使用改进的均匀近似方法和相位融合方法的标量和张量扰动方程为广义的Starobinsky通货膨胀模型，最高为偏差三阶。我们将结果与数值集成进行比较。我们已经获得了两种半经典方法都重现标量功率谱$ p_ {s，t} $，标量光谱索引$ n_s $和张量表与标准比率$ r $。另外，我们在$（n_s，r）$ plane中介绍了结果。
In this work we solved the equation of scalar and tensor perturbations for the generalized Starobinsky inflationary model using the improved uniform approximation method and the phase-integral method up to third-order in deviation. We compare our results with the numerical integration. We have obtained that both semiclassical methods reproduce the scalar power spectra $P_{S,T}$, the scalar spectral index $n_S$, and the tensor-to-scalar ratio $r$. Also we present our results in the $(n_S,r)$ plane.
