论文摘要
我们表明，在完整的弦乐理论中，在超对称的孤子背景上，四维设立空间是一个格劳伯山状态，即连贯的状态。我们认为，这种状态仅在时间上不同程度的自由度和包括量子校正的情况下才实现，而超对称性自发折断。另一方面，由此产生的DE Sitter空间的波动受Agarwal-Tara状态的控制，该状态是重力（和Flux）增添的相干状态。一旦将de Sitter空间实现为连贯的状态，而不是真空，它的能力就可以脱离滚动，以及有关其（元）稳定性，真空能量和有限熵的问题似乎具有明确的分辨率。
We show that four-dimensional de Sitter space is a Glauber-Sudarshan state, i.e. a coherent state, over a supersymmetric solitonic background in full string theory. We argue that such a state is only realized in the presence of temporally varying degrees of freedom and including quantum corrections, with supersymmetry being broken spontaneously. On the other hand, fluctuations over the resulting de Sitter space is governed by the Agarwal-Tara state, which is a graviton (and flux)-added coherent state. Once de Sitter space is realized as a coherent state, and not as a vacuum, its ability to remain out of the swampland as well as issues regarding its (meta)stability, vacuum energy, and finite entropy appear to have clear resolutions.
