论文摘要
我们在十维字符串模型中研究Sitter配置，其中超对称性在弦尺度上是不对称的。为此，我们得出了具有局部源的宇宙学常数的表达式，其局部源是局部源的表达式，这些源源产生了无需定理，可以扩展对超对称病例的先前作品。我们将结果置于维度的降低范围内，并将其连接到许多Swampland的猜想，在没有超对称性的情况下进一步证实了它们。此外，我们在不稳定的抗DE保姆景观中构建了自上而下的brane-world宇宙学的嵌入，从而提供了最近重新审视的建议的具体实现。
We study de Sitter configurations in ten-dimensional string models where supersymmetry is either absent or broken at the string scale. To this end, we derive expressions for the cosmological constant in general warped flux compactifications with localized sources, which yield no-go theorems that extend previous works on supersymmetric cases. We frame our results within a dimensional reduction and connect them to a number of Swampland conjectures, corroborating them further in the absence of supersymmetry. Furthermore, we construct a top-down string embedding of de Sitter brane-world cosmologies within unstable anti-de Sitter landscapes, providing a concrete realization of a recently revisited proposal.
