论文摘要
我们在数字上调查了二次通胀后的重新加热，最多65个领域，重点是生产非高斯性。我们考虑几组初始条件，质量和衰减率。正如预期的那样，我们发现再加热阶段可能会对非高斯信号产生重大影响，但是对于这一数量的字段，可检测到的非高斯性水平需要以特定方式订购初始条件，质量范围和衰减速率。我们推测这是否可能会在N-Flalation限制中发生变化。
We numerically investigate reheating after quadratic inflation with up to 65 fields, focusing on the production of non-Gaussianity. We consider several sets of initial conditions, masses and decay rates. As expected we find that the reheating phase can have a significant effect on the non-Gaussian signal, but that for this number of fields a detectable level of non-Gaussianity requires the initial conditions, mass range and decay rates to be ordered in a particular way. We speculate on whether this might change in the N-flation limit.
