The research that the PIs intend to perform consists of several projects involving both formal and phenomenological aspects of String Theory and related theories of gravity, and supersymmetric gauge theories. The purpose of the proposed activity will be to extend our knowledge of fundamental physics, including but not limited to the structure of cosmic singularities like the Big Bang, the quantum nature of black holes, critical properties of gauge theories, and the relation between physics at very short distance scales characteristic of string theory and physics at scales observable in experiments. More specifically, the PI will conduct research aimed at understanding space-like singularities using holographic correspondences involving non-critical string theory, Matrix theory, and the AdS/CFT correspondence. He will also use scattering techniques to decode microstates of black holes. The co-PI will investigate the properties of strongly-coupled scaling limits of SUSY gauge theories, applying new techniques that he recently helped to develop. He will also study the structure of magnetically charged particles in SUSY gauge theories and the flows of a class of string-inspired gauge theories from high to low energies. Part of the funds will be used to invite leading workers in the field to visit the University of Kentucky to give seminars and to engage in detailed discussions, which could lead to future collaborations. A few distinguished visitors will be invited to deliver popular lectures aimed at encouraging young undergraduates to choose physics as a career and to disseminate frontier results in physics among a broad cross-section of the community.

PI 打算进行的研究包括几个项目，涉及弦理论和相关引力理论以及超对称规范理论的形式和现象学方面。拟议活动的目的是扩展我们的基础物理学知识，包括但不限于宇宙奇点的结构（如大爆炸）、黑洞的量子性质、规范理论的临界性质以及物理学之间的关系。弦理论和物理学在实验中可观察到的非常短距离尺度的特征。更具体地说，PI 将开展旨在使用涉及非关键弦理论、矩阵理论和 AdS/CFT 对应的全息对应来理解类空间奇点的研究。他还将使用散射技术来解码黑洞的微观状态。联合首席研究员将应用他最近帮助开发的新技术，研究 SUSY 规范理论的强耦合标度极限的性质。他还将研究 SUSY 规范理论中带磁粒子的结构以及一类受弦启发的规范理论从高能到低能的流动。部分资金将用于邀请该领域的领先工作者访问肯塔基大学举办研讨会并进行详细讨论，这可能会促成未来的合作。将邀请一些杰出的访客进行受欢迎的讲座，旨在鼓励年轻的本科生选择物理学作为职业，并在社会各界中传播物理学的前沿成果。
