论文摘要
在这篇论文中，我们研究了在弦真空上断裂的巨大后果的某些方面。特别是，我们专注于十维字符串模型的真空稳定性问题，其扰动光谱不含tachyons。在第2章中制定了危险的模型之后，我们在第3章中介绍了它们的低能量有效描述，为经典运动方程提供了许多真空解决方案。在第4章中，我们分析了它们的经典稳定性，研究线性化的场波动，在第5章中，我们转向了量子稳定性问题。在第6章中，我们将最终的不稳定性从勃雷动力学（Brane Dynamics）角度构建，检查了棕褐色的相互作用和反向反应的几何形状。在第7章中，我们提出了一种将散装不稳定性与双重重归其化组流相连的全息对数，我们探索了涉及世界体积仪表理论的潜在具体场景。最后，在第8章中，我们转向宇宙学，得出了通用的无关结果，用于扭曲的通量压实，并沿着最近的建议的界线炮制了brane-world的场景，从而提供了这种类型结构的字符串理论嵌入。在第9章中，我们提供了一个摘要，并收集了一些结论性的评论。
In this thesis we investigate some aspects of the dramatic consequences of supersymmetry breaking on string vacua. In particular, we focus on the issue of vacuum stability in ten-dimensional string models with broken, or without, supersymmetry, whose perturbative spectra are free of tachyons. After formulating the models at stake in Chapter 2, we introduce their low-energy effective description in Chapter 3, presenting a number of vacuum solutions to the classical equations of motion. In Chapter 4 we analyze their classical stability, studying linearized field fluctuations, and in Chapter 5 we turn to the issue of quantum stability. In Chapter 6 we frame the resulting instabilities in terms of brane dynamics, examining brane interactions and back-reacted geometries. In Chapter 7 we propose a holographic correspondence connecting bulk instabilities with dual renormalization group flows, and we explore a potentially concrete scenario involving world-volume gauge theories. Finally, in Chapter 8 we turn to cosmology, deriving generalized no-go results for warped flux compactifications and concocting a brane-world scenario along the lines of a recent proposal, providing a string-theoretic embedding of constructions of this type. In Chapter 9 we provide a summary and collect some concluding remarks.
