This project in theoretical high energy physics will deal with quantum chromodynamics (QCD), the theory of interactions of quarks and gluons, topological aspects of field theory, and superunification theory. The project is divided into three parts: (1) a study of various topological aspects of quantum physics (quantum mechanics and field theory, particle and condensed matter physics), a study of fundamental problems in superstring theory, and a study of some phenomenological consequences of superunification; (2) a study of the long-range structure of the QCD plasma and its phenomenological consequences for heavy ion collisions, the evolution of the universe, and the dynamics of neutron stars; (3) a study of the phenomenology of confined QCD. All of these studies deepen and broaden our understanding of the fundamental interactions of matter. Several of them are quite important to our understanding of the strong (nuclear) interactions of quarks.

理论高能物理的这个项目将涉及量子色动力学(QCD)、夸克和胶子相互作用的理论、场论的拓扑方面和超统一理论。该项目分为三个部分：(1)研究量子物理的各种拓扑方面(量子力学和场论，粒子和凝聚态物理)，研究超弦理论中的基本问题，以及研究超统一的一些唯象结果；(2)QCD等离子体的长程结构及其对重离子碰撞、宇宙演化和中子星动力学的唯象结果的研究；(3)受限QCD的唯象研究。所有这些研究都加深和拓宽了我们对物质基本相互作用的理解。其中几个对我们理解夸克的强(核)相互作用非常重要。
