This RUI award funds the research activities of Professor Stephen G. Naculich at Bowdoin College.Supersymmetry is a mathematical symmetry that relates bosons, or particles with integer spin, to fermions, or particles with half-integer spin. Since its original mathematical formulation in the early 1970's, supersymmetry has played a significant role in numerous branches of high-energy physics and string theory. Indeed, most of the major advances that have occurred in understanding the properties of difficult strongly-coupled systems have occurred when these systems are analyzed in a supersymmmetric context. Supersymmetry also plays an integral role in string theory, and it is still an open question whether string theories are consistent without supersymmetry. In this project, Professor Naculich aims to study the connections between supersymmetric field theories and string theory. Specifically, he proposes to focus on both perturbative and non-perturbative aspects of supersymmetric gauge theory and supergravity theory, as illuminated by their connection to string theory through Dirichlet-branes (D-branes) and the AdS/CFT correspondence.The research is also envisioned to have several broader impacts. The insights gained, which will be disseminated through journal publications, seminars, and conference proceedings, will contribute to better control over higher-loop effects of gauge theories. This is essential to understanding the predictions of quantum chromodynamics (QCD), as well as to a deeper and more fundamental understanding of string theory. Because this project integrally involves undergraduate participation, it will also contribute to the education of undergraduates by providing training in quantum mechanics, group theory, and field theory, and exposure to research methods in theoretical physics.

该RUI奖资助Stephen G.超对称性是一种数学对称性，它将玻色子或具有整数自旋的粒子与费米子或具有半整数自旋的粒子联系起来。自20世纪70年代初的数学表述以来，超对称性在高能物理学和弦理论的许多分支中发挥了重要作用。事实上，在理解困难的强耦合系统的性质方面所取得的大多数重大进展都是在超对称背景下分析这些系统时发生的。超对称性在弦理论中也扮演着不可或缺的角色，而没有超对称性的弦理论是否是相容的，仍然是一个悬而未决的问题。 在这个项目中，Naculich教授旨在研究超对称场论与弦理论之间的联系。具体而言，他建议关注超对称规范理论和超引力理论的微扰和非微扰方面，正如它们通过Dirichlet膜（D膜）和AdS/CFT对应与弦理论的联系所阐明的那样。所获得的见解将通过期刊出版物、研讨会和会议论文集传播，这将有助于更好地控制规范理论的高环效应。这对于理解量子色动力学（QCD）的预测以及对弦理论更深入、更根本的理解至关重要。因为这个项目整体涉及本科生的参与，它也将有助于本科生的教育，提供培训，在量子力学，群论，场论，并接触到理论物理学的研究方法。
