AI总结:

本文通过规范/引力对偶性方法构建了胶球膨胀模型,探讨了超慢滚膨胀性态。

摘要:

我们总结了利用规范/引力对偶性方法构建胶球膨胀模型的工作。我们回顾了相关的五维一致截断的IIB超引力理论。我们考虑了这种有效理论中的解,其度规形式为一个径向方向上的dS_4展开。通过在这些解周围引入小(在适当意义上)的时间依赖变形,可以构建胶球膨胀模型。我们讨论了一个特定的变形解,描述了超慢滚膨胀性态。

英文摘要:

We summarize our work on building glueball inflation models with the methods of the gauge/gravity duality. We review the relevant five-dimensional consistent truncation of type IIB supergravity. We consider solutions of this effective theory, whose metric has the form of a $dS_4$ foliation over a radial direction. By turning on small (in an appropriate sense) time-dependent deformations around these solutions, one can build models of glueball inflation. We discuss a particular deformed solution, describing an ultra-slow roll inflationary regime.
