论文摘要
预计下一代宇宙学观察结果将改善与早期宇宙中原始通货膨胀相关的数量的测量。这些数量包括例如改进原始功率谱的标量曲率光谱指数的测量值,并可以更好地了解原始光谱的缩放依赖性。这包括倾斜的运行以及可能的运行。在本文中,我们研究了在温暖通货膨胀的背景下产生大型运行的可能性。运行的有用的分析表达式是在强大耗散制度的温暖通货膨胀的背景下得出的。将结果与最近在文献中引起的一些积极进取的原始充气电位进行比较并讨论。
Next generation of cosmological observations are expected to improve the measurements of several quantities connected to the primordial inflation in the early Universe. These quantities include for example improved measurements for the spectral index of the scalar curvature of the primordial power spectrum and to also bring a better understanding on the scaling dependence of the primordial spectrum. This includes the running of the tilt and, possibly, also the running of the running. In this paper, we investigate the possibility of generating large runnings in the context of warm inflation. Useful analytical expressions for the runnings are derived in the context of warm inflation in the strong dissipation regime. The results are compared to and discussed for some well motivated primordial inflaton potentials that have recently been of interest in the literature.
