项目摘要
This award funds the research activities of Professor Cumrun Vafa at Harvard University. The gravitational force is a key cornerstone of physics. Yet, when combined with quantum mechanics (the theory that governs the physics of the subatomic world), gravitational interactions lead to many puzzles. These puzzles are ultimately resolved within string theory, as a result of which string theory is perhaps the leading candidate for unifying gravity with quantum physics. One consequence of this resolution is that many possible particles and forces that could have existed in principle (and thus be part of the string-theory "landscape" of self-consistent theories) actually turn out to be forbidden (and thus are considered to belong to the so-called "swampland"). As part of this research, Professor Vafa will attempt to demystify the reasons why some theories belong to the swampland and not the landscape. The results of this research will therefore lead to a deeper understanding of how gravity works. As such, research in this area advances the national interest by promoting progress in fundamental aspects of science. This research is also envisioned to have significant broader impacts. Professor Vafa plans to continue his freshman seminar course, "Physics, Math and Puzzles", by teaching it once a year. This course aims to showcase deep principles of physics through simple mathematical puzzles. Professor Vafa also plans to give public lectures on these topics (based on a book he has just published). Moreover, Professor Vafa plans to continue running the Simons Center for Geometry and Physics summer workshops at Stony Brook University. These workshops will therefore continue to have a deep impact in educating some of the best young minds interested in theoretical physics, especially in questions related to string theory and the nearby areas of condensed-matter physics and mathematics. Professor Vafa also plans to continue delivering and participating in public forums to inform the public of progress being made in string theory and how it impacts our understanding of our universe.More technically, Professor Vafa will focus on elaborating the principles of the swampland and their connection to basic principles of quantum gravity, such as black-hole physics and unitarity. He will focus on drawing lessons from the supersymmetric examples of string compactifications, such as Calabi-Yau manifolds, where the most analytic control exists. A central aim for this research will be to explain why there is an upper bound on the number of massless particles we can get in supergravity theories, as well as the types of gauge forces and matter content we can obtain in a consistent theory of quantum gravity. These lessons will shed light on the case which is most relevant to our universe, namely the non-supersymmetric theories.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.
该奖项资助了哈佛大学Cumrun Vafa教授的研究活动。 引力是物理学的重要基石。 然而,当与量子力学(支配亚原子世界物理学的理论)结合时,引力相互作用会导致许多谜题。 这些难题最终在弦理论中得到解决,因此弦理论可能是统一引力与量子物理的主要候选者。 这种分解的一个结果是,许多可能的粒子和力原则上本来是存在的(因此是自洽理论的弦理论“景观”的一部分),实际上却被禁止了(因此被认为属于所谓的“沼泽地”)。 作为这项研究的一部分,Vafa教授将试图揭开一些理论属于沼泽而不是景观的原因。 因此,这项研究的结果将有助于更深入地了解重力是如何工作的。 因此,这一领域的研究通过促进科学基本方面的进步来促进国家利益。 预计这项研究也将产生更广泛的影响。 Vafa教授计划继续他的新生研讨会课程,“物理,数学和谜题”,每年教授一次。本课程旨在通过简单的数学谜题展示物理学的深层原理。 Vafa教授还计划就这些主题进行公开讲座(根据他刚刚出版的一本书)。 此外,瓦法教授计划继续在斯托尼布鲁克大学举办西蒙斯几何和物理中心的夏季讲习班。 因此,这些讲习班将继续在教育一些对理论物理感兴趣的最优秀的年轻人方面产生深远的影响,特别是在与弦理论以及凝聚态物理和数学的邻近领域有关的问题方面。 Vafa教授还计划继续提供和参与公共论坛,告知公众弦理论的进展以及它如何影响我们对宇宙的理解。更技术性地,Vafa教授将专注于阐述沼泽地的原理及其与量子引力基本原理的联系,如黑洞物理学和幺正性。 他将专注于从弦紧化的超对称例子中吸取教训,例如卡-丘流形,那里存在最多的解析控制。 这项研究的一个中心目标是解释为什么我们在超引力理论中可以得到的无质量粒子的数量有一个上限,以及我们在量子引力的相容理论中可以得到的规范力和物质含量的类型。 这些经验教训将阐明与我们的宇宙最相关的案例,即非超对称理论。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
