标题： Cosmology of light towers and swampland constraints

摘要： 我们研究了FLRW宇宙学在存在标量轻态塔和 runaway 指数势的情况下动力学演化。一些吸引子解从有效场论的角度来看具有有问题的行为，我们利用这些行为来论证对势和塔特征质量指数缩放的可能限制，当向模空间的渐近区域移动时。这些进一步表明塔的质量不应比势或与单一紧致维度的齐次去紧化相关的KK尺度衰减得更快。我们通过不同的自上而下的紧化提供支持，并与文献中先前发现的论点相联系。 显示英文摘要

摘要： We study the dynamical evolution of FLRW cosmologies in the presence of a tower of scalar light states and a runaway exponential potential. Some of the attractor solutions have problematic behaviours from the EFT point of view, which we use to argue for restrictions on the possible exponential scalings of the potential and tower characteristic mass as we move towards asymptotic regions in moduli space. These serve as further evidence that the tower mass should not decay faster than the potential or the KK scale associated to the homogeneous decompactification of a single compact dimension. We provide support from different top-down compactifications and connect with previous arguments found in the literature.
