使用 IIB 型弦理论中非微扰体积稳定的 10D 提升,我们研究了获得德西特真空的局限性。基于此,我们发现由高吉诺凝聚稳定的单一卡勒模量的最简单的KKLT真空不能提升到德西特。相反,由于体积模量的反反应比之前预期的更强,隆起变得平坦,导致真空处于亚稳态和SUSY断裂,但总是AdS。然而,我们还表明,赛道稳定等设置可以避免这个问题。在这些模型中,可以获得超对称 AdS 真空,其宇宙学常数可以调为零,同时保持有限模稳定性。在这种情况下,德西特隆起似乎是可能的,而内部体积的反作用可以忽略不计。我们也从 10D 角度展示了这种行为。
Using a 10D lift of non-perturbative volume stabilization in type IIB string theory we study the limitations for obtaining de Sitter vacua. Based on this we find that the simplest KKLT vacua with a single Kahler modulus stabilized by a gaugino condensate cannot be uplifted to de Sitter. Rather, the uplift flattens out due to stronger backreaction on the volume modulus than has previously been anticipated, resulting in vacua which are meta-stable and SUSY breaking, but that are always AdS. However, we also show that setups such as racetrack stabilization can avoid this issue. In these models it is possible to obtain supersymmetric AdS vacua with a cosmological constant that can be tuned to zero while retaining finite moduli stabilization. In this regime, it seems that de Sitter uplifts are possible with negligible backreaction on the internal volume. We exhibit this behavior also from the 10D perspective.
