AI总结:

本文扩展了de Sitter猜想以考虑标量场动力学,应用于第五要素模型膨胀,得到更宽的标量势参数允许区域,对构造紧致化模型有潜在影响。

摘要:

de Sitter猜想为一致的量子引力可能真空设定了严格的限制。我们通过考虑标量场的动力学扩展了de Sitter猜想,然后将这种扩展的de Sitter猜想应用于其中标量场动力学至关重要的第五要素模型的膨胀模型,从而获得比传统de Sitter猜想所考虑的情况更宽的标量势参数允许区域。swampland猜想中的新限制可能在构造紧致化模型的多种情况下具有影响。

英文摘要:

The de Sitter conjecture yields a severe bound on possible vacua for a consistent quantum gravity. We extend the de Sitter conjecture by taking into account dynamics of the scalar field. We then apply such an extended de Sitter conjecture to a quintessence model of inflation for which dynamics of the scalar field is essential, and obtain an allowed region of parameters of the scalar potential wider than previously considered cases with the conventional de Sitter conjecture. The new bounds in the swampland conjecture could have implications in several situations to construct compactification models.
