This award funds the research activities of Professor Edward Witten and a group of postdoctoral researchers at the Institute for Advanced Study in Princeton.The project is devoted to the study of elementary particle physics, including its connections to other areas of study ranging from astrophysics and cosmology to condensed-matter physics and geometry. Current and planned work of the researchers supported by this grant covers a very wide range of topics, including the connections between gauge theory (the modern language of the physics governing the elementary particles), string theory (a speculative proposal for unifying the fundamental forces of nature), and geometry. These researchers will also study the possibilities for new models of particle physics that might be relevant at current and future particle-physics experiments; new methods of computing and studying the ways in which elementary particles scatter off each other; new experimental hints of the cosmic dark matter which makes up most of the matter in the universe; and more. Research in these areas thus advances the national interest by promoting the progress of science in one of its most fundamental directions: the discovery and understanding of new physical laws. This project will also have significant broader impacts. The postdoctoral fellows supported by this project will also gain experience working at a high level on these exciting scientific problems, which have all attracted great interest nationally and internationally.More technically, Professor Witten's recent and ongoing work has involved operator algebras that give a new perspective on black-hole entropy and on the nature of de Sitter space in quantum theory. The postdoctoral fellows supported by this project have a wide range of interests and work with each other on frontier topics in theoretical high-energy physics as well as with Professor Witten and other local faculty.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项资助爱德华维滕教授和普林斯顿高级研究所的一批博士后研究人员的研究活动，该项目致力于基本粒子物理学的研究，包括其与天体物理学和宇宙学、凝聚态物理学和几何学等其他研究领域的联系。 由该资助支持的研究人员目前和计划的工作涵盖了非常广泛的主题，包括规范理论（管理基本粒子的现代物理学语言），弦理论（统一自然基本力的投机性建议）和几何之间的联系。 这些研究人员还将研究可能与当前和未来粒子物理实验相关的粒子物理新模型的可能性;计算和研究基本粒子相互散射方式的新方法;宇宙暗物质的新实验提示，它构成了宇宙中大部分物质;等等。 因此，这些领域的研究通过促进科学在其最基本的方向之一的进步来促进国家利益：发现和理解新的物理定律。 该项目还将产生广泛的影响。 由该项目支持的博士后研究员也将获得在这些令人兴奋的科学问题上的高水平工作的经验，这些问题在国内和国际上都引起了极大的兴趣。从技术上讲，维滕教授最近和正在进行的工作涉及算子代数，为黑洞熵和量子理论中的de Sitter空间的性质提供了新的视角。 该项目支持的博士后研究员兴趣广泛，在理论高能物理的前沿课题上相互合作，并与维滕教授和其他当地教师合作。该奖项反映了NSF的法定使命，通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
