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.

该奖项为肯塔基大学的Sumit Das教授和Alfred Shapere教授的研究活动提供资金。该项目涉及使用弦理论和量子场理论的技术来了解近相过渡的系统的重力和系统的量子性能。近年来，如字符串理论和常规量子系统所描述的那样，物理学家发现了量子重力之间存在亲密关系。这种关系已被用来了解相当复杂的系统的许多平衡和接近平衡的特性，例如超导体或在高温下使用字符串理论在高温下碰撞重离子。本提案涉及新的方法，这些方法将阐明这些系统的性质远非均衡。 同时，该提案旨在通过将这些方面与可以使用常规量子力学方法进行研究的系统联系，以更深入地了解重力的量子方面。在平行的方向上，有力的超对称方法将用于对相位过渡及其相关的普遍行为进行分类。该项目的更广泛的影响包括培训研究生和博士后在尖端的研究技术中的培训，并为研究职业做准备。 调查人员将向所有人开放的研究讲座和研讨会，并将其研究活动中收集的思想纳入他们教授的课程。 调查人员还将继续他们的工作，以使肯塔基大学的物理课程现代化，并使学生与这些学科的Frontier Research接触。
