论文摘要
我们在弦理论中构建了纯粹的非扰动抗DE保姆真空吸尘器，在提升到De Sitter（DS）时，衰减时间比标准结构的衰减时间要小，例如KKLT和LVS场景。这些真空由于纯粹由非扰动术语构建，避免了某些障碍物困扰着弦理论中DS的其他结构。这导致了一类新的现象学DS真空吸尘器，具有新颖的独特特征，例如具有两个最大值。在检查了这些振奋人心的DS Vacua是否服从TCC之后，我们重新审视了DS空间作为真空的一些旧问题。我们发现，不仅在现象学上很难构建与TCC兼容的真空吸尘器，而且在这种结构中以及其他问题以及其他问题中也出现了固有的自由度的固有时间依赖。这加强了这样一种观念，即如果DS存在于字符串理论中，则应该是Glauber-Sudarshan状态，而不是真空。
We construct purely non-perturbative anti-de Sitter vacua in string theory which, on uplifting to a de Sitter (dS) one, have a decay time many orders of magnitude smaller than those of standard constructions, such as the KKLT and LVS scenarios. By virtue of being constructed purely from non-perturbative terms, these vacua avoids certain obstructions plaguing other constructions of dS in string theory. This results in a new class of phenomenological dS vacua in string theory with novel distinctive characteristics such as having two maxima. After examining whether these uplifted dS vacua obey the TCC, we revisit some old problems of realization of dS space as a vacuum. We find that not only is it phenomenologically hard to construct TCC-compatible vacua, but also inherent temporal dependences of the degrees of freedom generically arise in such constructions, amongst other issues. This reinforces the idea that dS, if it exists in string theory, should be a Glauber-Sudarshan state and not a vacuum.
