项目摘要

This award funds the research activities of Professors Eric D'Hoker, Michael Gutperle, and Per Kraus at the University of California, Los Angeles. String theory remains the most promising candidate for the unification of the Standard Model of elementary particles with General Relativity, the theory of gravitational forces, in a framework consistent with the laws of Quantum Mechanics. Developments in string theory over the past decades have spawned progress in many areas of physics and mathematics, thereby serving the national interest by promoting the progress of science in one of its most fundamental directions: the discovery and understanding of new physical laws. Professors D'Hoker, Gutperle, and Kraus aim to deepen the understanding of string theory, quantum gravity, and black-hole physics by exploring new symmetry principles, new connections with pure mathematics, and by performing sophisticated calculations at the frontier of string theory. This project will also have significant broader impacts. String theory continues to attract and inspire some of the brightest graduate students and postdocs in physics, and Professors D'Hoker, Gutperle, and Kraus will involve graduate students and postdocs in their research while actively mentoring them on their path to becoming professional scientists. Workshops organized with other universities in Southern California will serve to introduce junior physicists at UCLA to the broader community of researchers, while interactions with students during visits to local middle and high schools will promote public outreach. At a more technical level, Professor D'Hoker continues to advance the subject of superstring perturbation theory, its applications to the low-energy effective interactions of supergravity, and its implications for the high-energy behavior of string amplitudes. Professor Gutperle will investigate five-dimensional super-conformal field theories, as well as domain wall, surface, and line operators in conformal field theories utilizing the AdS/CFT correspondence. Professor Kraus will study conformal field theories in various dimensions, with an emphasis on elucidating structures that have implications for quantum gravity via the AdS/CFT correspondence. Professors D'Hoker, Gutperle, and Kraus will also use conformal-bootstrap methods to study the properties of the conformal field theory which is holographically dual to Type IIB string theory on AdS3.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.

该奖项为埃里克·德·霍克（Eric D'Hoker），迈克尔·古特尔（Michael Gutperle）教授和加利福尼亚大学洛杉矶分校的Per Kraus提供了研究活动。在与量子力学定律一致的框架中，弦理论仍然是将基本粒子标准模型统一的最有前途的候选者。在过去的几十年中，弦理论的发展在许多物理和数学领域都产生了进步，从而通过以其最根本的方向之一来促进科学的进步来为国家利益提供服务：对新物理定律的发现和理解。 D'Hoker教授，Gutperle和Kraus旨在通过探索新的对称原理，纯粹的数学联系，并在字符串理论的边界进行复杂的计算，从而加深对弦理论，量子重力和黑洞物理学的理解。该项目还将产生更广泛的影响。弦理论继续吸引和激发一些物理学上最聪明的研究生和博士后，D'Hoker，Gutperle和Kraus教授将涉及研究生和博士学位的研究，同时积极地指导他们成为专业科学家的道路。与南加州其他大学组织的研讨会将有助于将加州大学洛杉矶分校的初级物理学家介绍给更广泛的研究人员社区，而在访问当地中学和高中期间与学生的互动将促进公共宣传。从技术层面上讲，D'Hoker教授继续推进SuperString扰动理论的主题，其在低能性有效相互作用中的应用以及其对弦振幅的高能行为的影响。 Gutperle教授将利用ADS/CFT对应关系研究五维超符合田间理论，以及在共形场理论中的域壁，表面和线算子。克劳斯教授将在各个方面研究保形场理论，重点是阐明通过ADS/CFT对应关系对量子重力产生影响的结构。 Professors D'Hoker, Gutperle, and Kraus will also use conformal-bootstrap methods to study the properties of the conformal field theory which is holographically dual to Type IIB string theory on AdS3.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.
