标题： Strengthening the de Sitter swampland conjecture in warm inflation

摘要： 与超弦理论一致的有效标量场理论空间上的“de Sitter约束”为支配宇宙演化的标量场势的斜率提供了一个下限，例如，一个假设的暴胀场。 虽然规范化的单标量场暴胀模型不符合这一约束，但最近文献中声称，在大耗散的情况下，热暴胀模型可以与之兼容。 已知de Sitter约束来源于熵的考虑。 由于热暴胀必然涉及熵产生，因此有必要确定这种熵产生将如何影响由沼泽地条件施加的约束。 在这里，我们将这些熵的考量推广到热暴胀的情况，并表明势的斜率条件基本保持不变，因此即使在热暴胀动力学中也是稳健的。 由此我们可以得出结论，热暴胀模型确实可以与“沼泽地”标准相一致。 显示英文摘要

摘要： The "de Sitter constraint" on the space of effective scalar field theories consistent with superstring theory provides a lower bound on the slope of the potential of a scalar field which dominates the evolution of the Universe, e.g., a hypothetical inflaton field. Whereas models of single scalar field inflation with a canonically normalized field do not obey this constraint, it has been claimed recently in the literature that models of warm inflation can be made compatible with it in the case of large dissipation. The de Sitter constraint is known to be derived from entropy considerations. Since warm inflation necessary involves entropy production, it becomes necessary to determine how this entropy production will affect the constraints imposed by the swampland conditions. Here, we generalize these entropy considerations to the case of warm inflation and show that the condition on the slope of the potential remains essentially unchanged and is, hence, robust even in the warm inflation dynamics. We are then able to conclude that models of warm inflation indeed can be made consistent with the "swampland" criteria.
