标题： Stochastic gravitational waves backgrounds: a probe for inflationary and non-inflationary cosmology

摘要： 考察了产生高能随机引力波背景的物理场景（频率范围从$\mu$赫兹到千兆赫兹）。在某些情况下，对数能量谱的典型幅度甚至可以比普通暴胀预测大八个数量级。讨论了产生的引力子能量密度在频率依赖关系上的标度破缺现象。 显示英文摘要

摘要： Physical scenarios, leading to highly energetic stochastic gravitational waves backgrounds (for frequencies ranging from the $\mu$Hz up to the GHz) are examined. In some cases the typical amplitude of the logarithmic energy spectrum can be even eight orders of magnitude larger than the ordinary inflationary prediction. Scaling violations in the frequency dependence of the energy density of the produced gravitons are discussed.
