This award funds the research activities of Professors Jacques Distler, Willy Fischler, Can Kilic, Sonia Paban and Steven Weinberg of the Theory Group at the University of Texas at Austin.Since its foundation, the Theory Group has had a strong track record of conducting research on a broad range of topics with the goal of exploring the fundamental laws of nature. These topics include the dynamics of the very early universe, the relationship between information and black holes (which may lead to crucial insights into the fundamental theory of gravity), the possible extensions of the Standard Model of particle physics (which describes all known particles and their interactions) and the experimental signatures of such extensions, and the exploration of string theory and formal aspects of quantum field theory. This diversified effort to improve our understanding of nature at the deepest levels is well aligned with the goal of advancing the national interest by maintaining and further boosting the role of the United States as the global leader in theoretical high-energy physics. The Theory Group is also actively committed to making physics accessible to a wider audience and achieving a substantial impact outside of academia. This is achieved through popular lectures given to live audiences as well as over other media, through the publication of books at both the public and technical levels, and through the development of web technologies. In addition, the Theory Group takes pride in the training of graduate students and postdocs who continue on to successful careers in this field.Specifically, the avenues of research to be conducted during the term of this project include, but are not limited to, the following: Distler will extend the classification of N=2 four-dimensional superconformal field theories and explore a generalization of important results in topological string theory. Fischler will continue his exploration of the physical effects of theta angles on black hole horizons and their experimental signatures as seen by observers hovering at a fixed distance from black holes. He will complete his research on the effects of shockwaves in de Sitter space and the implications for holographic information. He will study the description of mixmaster universes in the context of AdS/CFT. Fischler will also continue his longstanding work on holographic space-time and revisit the initial conditions for inflation. Kilic will explore aspects of collider physics as well as models of dark matter and their experimental signatures. Paban will study theories of inflation with many fields and the conditions under which they reach the adiabatic limit at the end of inflation. Weinberg will continue the search for a modified version of quantum mechanics that will avoid the usual unsatisfactory aspects while retaining the successes of the existing theory.

该奖项资助了德克萨斯大学奥斯汀分校理论小组的Jacques Distler、Willy Fischler、Can Kilic、Sonia Paban和Steven温伯格教授的研究活动。自成立以来，理论小组在探索自然基本规律的广泛主题方面有着良好的研究记录。 这些主题包括非常早期宇宙的动力学，信息和黑洞之间的关系（这可能导致对引力基本理论的重要见解），粒子物理学标准模型的可能扩展（描述所有已知粒子及其相互作用）和这种扩展的实验签名，以及弦理论和量子场论的形式方面的探索。 这种旨在提高我们对自然最深层次理解的多元化努力，与通过保持和进一步提升美国作为理论高能物理学全球领导者的作用来促进国家利益的目标是一致的。 理论小组还积极致力于使物理学更广泛的受众，并实现学术界以外的重大影响。 这是通过向现场观众以及其他媒体提供的受欢迎的讲座，通过出版公共和技术层面的书籍，以及通过开发网络技术来实现的。 此外，理论小组以培养研究生和博士后谁继续在这一领域取得成功的职业生涯感到自豪。具体来说，在本项目期间进行的研究途径包括，但不限于，以下： Distler将扩展N=2四维超共形场论的分类，并探索拓扑弦理论中重要结果的推广。Fischler将继续探索θ角对黑洞视界的物理影响，以及在距离黑洞固定距离处徘徊的观察者所看到的实验特征。他将完成他对德西特空间中冲击波的影响和全息信息的影响的研究。他将在AdS/CFT的背景下研究mixmaster宇宙的描述。Fischler还将继续他在全息时空方面的长期工作，并重新审视暴胀的初始条件。 Kilic将探索对撞机物理学的各个方面，以及暗物质模型及其实验特征。 帕班将研究理论的通货膨胀与许多领域和条件下，他们达到绝热极限年底的通货膨胀。 温伯格将继续寻找量子力学的修正版本，它将避免通常不令人满意的方面，同时保留现有理论的成功。
