标题： Dynamical de Sitter conjecture and quintessence

摘要： de Sitter 猜想对一致量子引力的可能真空态施加了严格的限制。 我们通过考虑标量场的动力学来扩展 de Sitter 猜想。 然后我们将这一扩展后的 de Sitter 猜想应用于标量场动力学至关重要的暴胀 quintessence 模型，并得到了比以往使用传统 de Sitter 猜想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建紧化模型的几种情况下具有重要意义。 显示英文摘要

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.
