论文摘要
我们构建了非线性充气势能密度，这些密度描述了不必要的非常慢的封闭和开放通货膨胀模型，并计算这些模型在通货膨胀期间量子机械波动随后倾斜的原始空间不均匀功率谱。较早的非平原通货膨胀模型功率谱计算假设具有线性斜率的充气势能密度，从而导致通货膨胀期间产生非常慢的滚动，直到功率谱。这些新的倾斜功率谱与以前用于研究非平板宇宙学模型中宇宙学数据的功率谱不同。
We construct non-linear inflaton potential energy densities that describe not-necessarily very-slowly-rolling closed and open inflation models, and compute tilted primordial spatial inhomogeneity power spectra that follow from quantum mechanical fluctuations during inflation in these models. Earlier non-flat inflation model power spectra computations assumed an inflaton potential energy density with a linear slope that resulted in very-slow-roll during inflation and untilted power spectra. These new tilted power spectra differ from those that have previously been used to study cosmological data in non-flat cosmological models.
