This award funds the research activities of Professors Sumit Das and Alfred Shapere at the University of Kentucky.This project involves the use of techniques of string theory and quantum field theory to understand quantum properties of gravity and properties of systems near phase transitions. In recent years, physicists have discovered an intimate relationship between quantum gravity as described by string theory and conventional quantum systems. This relationship has been used to understand many equilibrium and near-equilibrium properties of rather complicated systems near phase transitions, like superconductors or colliding heavy ions at high temperature, using methods of string theory. The present proposal involves novel methods which will shed light on properties of these systems far from equilibrium. At the same time, the proposal aims to develop a deeper understanding of the quantum aspects of gravity by relating such aspects to systems which can be investigated using conventional methods of quantum mechanics. In a parallel direction, powerful methods of supersymmetry will be used to classify phase transitions and their related universal behavior.The broader impacts of this project include the training of graduate students and postdocs in cutting-edge research techniques and preparing them for research careers. The investigators will give lectures and seminars on their research which are open to all, and will incorporate ideas gleaned from their research activities in the courses they teach. The investigators will also continue their work to modernize the University of Kentucky's physics curriculum and to bring its students into contact with frontier research in these subjects.

该奖项资助肯塔基大学 Sumit Das 和 Alfred Shapere 教授的研究活动。该项目涉及使用弦理论和量子场论技术来理解引力的量子特性和接近相变的系统的特性。近年来，物理学家发现了弦理论所描述的量子引力与传统量子系统之间的密切关系。这种关系已被用来使用弦理论的方法来理解相变附近相当复杂的系统的许多平衡和近平衡特性，例如超导体或高温下的碰撞重离子。目前的提议涉及新颖的方法，这些方法将揭示这些远离平衡的系统的特性。 同时，该提案旨在通过将重力的量子方面与可以使用量子力学的传统方法进行研究的系统联系起来，加深对这些方面的理解。在并行的方向上，强大的超对称方法将用于对相变及其相关的普遍行为进行分类。该项目的更广泛影响包括培训研究生和博士后尖端研究技术，并为他们的研究生涯做好准备。 研究人员将就他们的研究举办向所有人开放的讲座和研讨会，并将从他们的研究活动中收集到的想法纳入他们教授的课程中。 研究人员还将继续致力于使肯塔基大学的物理课程现代化，并让学生接触这些学科的前沿研究。
