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.

在过去的二十年中，弦理论一直是理论高能物理学最深入研究的领域之一。 这是正确的，主要是因为弦理论提供了目前最成功的将重力与其他基本力（强，弱和电磁）统一的方法。 弦理论的结果也散布在许多其他物理学的分支中，从而提高了对量表理论，凝结物理学和重离子物理学的了解。 弦理论还导致了数学上有力的新见解。 在这个项目中，Blanco-Pillado教授旨在将弦理论应用于宇宙学。 具体而言，他建议研究某种类别的弦模型的宇宙学含义（所谓的``通量压实''），特别关注四维潜力的复杂结构模量部分的影响。此项目还将产生更大的广泛影响。 除了拟议的研究的跨学科范围之外 - 通过弦理论范式连接高能物理学和宇宙学-------这个项目还将涉及对研究生进行培训，以在这一尖端的研究领域进行研究。
