AI总结:

该研究探讨了热耗散驱动的再加热过程对原初引力波谱的影响,提出通过观测引力波谱来探测再加热物理的新途径。

摘要:

为了使膨胀宇宙演变成热宇宙,需要一种称为再加热的过程。然而,再加热的精确机制仍不清楚。我们表明,如果再加热由热耗散效应触发,则原初引力波谱将出现特征性变化。这提出了通过观测来探测再加热物理的可能方法。

英文摘要:

In order for an inflationary universe to evolve into a hot universe, a process known as reheating is required. However, the precise mechanism of reheating remains unknown. We show that if the reheating is triggered by thermal dissipation effects, distinctive features appear in the spectrum of primordial gravitational waves. This suggests a possible way to observationally probe the physics of reheating.
