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.

PIS打算执行的研究包括涉及弦理论的形式和现象学方面的几个项目以及重力的相关理论以及超对称仪表理论。拟议活动的目的是扩展我们对基本物理学的了解，包括但不限于宇宙奇异性的结构，例如大爆炸，黑洞的量子性质，量规理论的关键特性以及在实验中可观察到的量表的非常短的距离量表特征和物理学的非常短的距离尺度特征和物理的物理之间的关系。更具体地说，PI将使用涉及非临界弦理论，矩阵理论和ADS/CFT对应的全息相应对应性进行旨在理解太空奇异性的研究。他还将使用散射技术来解码黑洞的微骨。 Co-Pi将研究Susy Gauge理论强耦合缩放限制限制的性能，并采用他最近帮助开发的新技术。他还将研究SUSY仪表理论中带有带电的颗粒的结构，以及一类弦乐仪从高能量到低能量的流动。部分资金将用于邀请该领域的主要工人访问肯塔基大学，进行研讨会并进行详细的讨论，这可能导致未来的合作。将邀请一些杰出的访客发表旨在鼓励年轻的大学生选择物理学的流行讲座，并在社区广泛的横截面中分配物理学的边界结果。
