This proposal requests support for a continuing program of research in important areas of QCD, including confinement, the deconfining phase of the quark gluon plasma, and the melting of heavy quarkonia at high temperatures. The principle method used by the PI is that of Lattice gauge theory, a dicretized numerical approach to calculating the relevant physical quantities from the underlying QCD theory.understanding confinement and the connection between QCD long- and short-distance behavior is an important problem. Likewise, understanding the deconfined phase and its thermalization, as encountered in experiments at RHIC, is an outstanding problemof current physics. Yet another aspect of RHIC physics is the melting of J/psi and the corresponding bottom quarkonia in the high temperatures generated by the heavy ion collisions. The broader impacts of this proposal include the training of students in state-of-the-art Computational physics, and the application of the computational techniques to other fields, condensed matter physics and biology in particular.

这个提议要求支持QCD重要领域的持续研究计划，包括禁闭，夸克胶子等离子体的退澄清阶段，以及高温下重夸克的熔化。PI使用的主要方法是格点规范理论，这是一种从基础QCD理论计算相关物理量的离散化数值方法。理解禁闭以及QCD长距离和短距离行为之间的联系是一个重要问题。同样地，理解在RHIC实验中遇到的退禁闭相及其热化，是当前物理学的一个突出问题。RHIC物理学的另一个方面是J/psi和相应的底夸克偶素在重离子碰撞产生的高温下的熔化。这一提议的更广泛影响包括培养学生掌握最先进的计算物理学，以及将计算技术应用于其他领域，特别是凝聚态物理学和生物学。
