9724831 Bars This award supports a three year collaborative research project between Professor Itzhak Bars of the University of Southern California, and Professor Tohru Eguchi of the University of Tokyo in Japan. The researchers will be undertaking studies relating to string theory and field theory dualities and integrable models. The objectives of the research are to study: (1) dualities of superstrings and super-p-branes and their role in non-perturbative computations in string theory, supersymmetric gauge theories and superconformal field theories in four dimensions, (2) theories with extended supersymmetries and hidden dimensions beyond ten which are crucial in the construction of the fundamental theory that lies behind string theory, (3) integrable models and their role in duality symmetries of field and string theories, representation theory of W- algebras and quantum gravity and (4) problems in condensed matter physics, such as the Kondo problem. This project brings together the efforts of two laboratories that have complementary expertise and research capabilities. The collaboration will unite the theoretical high energy physics group at the University of California with the theoretical group from the University of Tokyo. In addition, younger scientists will be included in the project. It is anticipated that the research could contribute further to an all-embracing theory of physical phenomena. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation. ***

该奖项支持南加州大学Itzhak Bars教授和日本东京大学Tohru Eguchi教授之间为期三年的合作研究项目。研究人员将进行有关弦理论和场论对偶性和可积模型的研究。本研究的目的是研究：(1)超弦和超对膜的对偶性及其在四维弦理论、超对称规范理论和超共形场论中的非摄动计算中的作用；(2)扩展超对称和隐藏维数超过10的理论，这对构建弦理论的基本理论至关重要；(3)可积模型及其在场和弦理论对偶对称性中的作用；W-代数的表示理论和量子引力；(4)凝聚态物理中的问题，如近藤问题。该项目汇集了两个具有互补专业知识和研究能力的实验室的努力。这项合作将联合加州大学的理论高能物理小组和东京大学的理论小组。此外，年轻科学家也将被纳入该项目。预计该研究将进一步有助于建立一个包罗万象的物理现象理论。通过思想和技术的交流，该项目将扩大我们的基础知识基础，促进国际了解与合作。* * *
