For the past two decades, string theory has been one of the most intensely investigated areas of theoretical high-energy physics. This is true chiefly because string theory offers what is currently the most successful method of unifying gravity with the other fundamental forces (strong, weak, and electromagnetic). Results from string theory have also spilled over into many other branches of physics, leading to improved understanding of gauge theories, condensed-matter physics, and heavy-ion physics. String theory has also led to powerful new insights in mathematics. In this project, Professor Blanco-Pillado aims to apply string theory to cosmology. Specifically, he proposes to study the cosmological implications of a certain class of string models (so-called ``flux compactifications''), paying particular attention to the effects of the complex structure moduli part of the four-dimensional potential.This project will also have significant broader impacts. Beyond the interdisciplinary reach of the proposed research --- connecting high-energy physics and cosmology through the paradigm of string theory --- this project will also involve the training of a graduate student to conduct research in this cutting-edge field of study.

在过去的二十年里，弦理论一直是理论高能物理研究最深入的领域之一。 确实如此，主要是因为弦理论提供了目前最成功的将引力与其他基本力（强力、弱力和电磁力）统一起来的方法。 弦理论的结果也渗透到物理学的许多其他分支，从而提高了对规范理论、凝聚态物理学和重离子物理学的理解。 弦理论也带来了数学领域强有力的新见解。 在这个项目中，布兰科-皮拉多教授旨在将弦理论应用于宇宙学。 具体来说，他建议研究某类弦模型（所谓的“通量紧化”）的宇宙学含义，特别关注四维势的复杂结构模部分的影响。该项目将也具有更广泛的影响。 除了拟议研究的跨学科范围（通过弦理论范式将高能物理学和宇宙学联系起来）之外，该项目还将培训一名研究生在这一前沿研究领域进行研究。
