U.S.-Japan Joint Seminar: Recent Developments in the Symmetry Aspects of Many-Body Physics

小行星9725948 该奖项支持美国科学家参与美国-拟于1998年8月在夏威夷举行的关于多体物理学对称性方面最新发展的日本讨论会。 共同组织者是麦迪逊的威斯康星州大学的Akif Baha Balantekin教授和日本东京大学的Takaharu Otsuka教授。 该研讨会的目的是汇集研究人员谁在核物理领域的工作，以及凝聚态物理讨论对称性原则在多体现象的实施。 重点将放在对称性的量子系统，其中包含相对较少的粒子数。 因此，在这些系统中，考虑系统所具有的对称性变得很重要，以便阐明系统的潜在动力学。 会议将集中讨论六个主题：（1）相互作用玻色子模型及其扩展所描述的核集体运动中的动力学对称性和超对称性;（2）电子多体系统中的对称性，包括介观系统和微团簇;（3）混沌和对称性破缺，量子可积系统;（4）对称性概念在滴线附近的核中的应用;（5）原子核的对称性。（5）相对论问题的对称性;（6）散射理论中的对称性。 研讨会的结果将确定该领域的新方向，启动美国和日本研究人员之间的新合作，并加强现有的合作。 与日本专家在这一领域的想法和数据交流将使美国参与者能够推进自己的工作，并为未来的合作项目奠定基础。 研讨会的组织者特别努力让研究生和博士后研究人员参加。 会议记录将在万维网上公布。 ***

9725948 Balantekin This award supports the participation of American scientists in a U.S.-Japan seminar on Recent Developments in the Symmetry Aspects of Many-Body Physics, to be held in Hawaii, in August, 1998. The co-organizers are Professors Akif Baha Balantekin of the University of Wisconsin in Madison and Professor Takaharu Otsuka of the University of Tokyo in Japan. The objective of the seminar is to bring together researchers who work in the field of nuclear physics as well as condensed matter physics to discuss implementation of symmetry principles in many-body phenomena. The focus will be on symmetries in quantum systems which contain relatively small number of particles. In these systems it therefore becomes important to consider the symmetries the system possesses, in order to clarify the underlying dynamics of the system. The session will focus on six theme topics: (l) dynamical symmetry and supersymmetry in nuclear collective motion as described by the interacting boson model and its extensions; (2) symmetry in electronic many-body systems including mesoscopic systems and micro-clusters; (3) chaos and broken symmetries, quantum integrable systems; (4) utility of symmetry concepts in nuclei near the drip lines; (5) symmetries of relativistic problems; and (6) symmetries in the scattering theory. Results of the seminar should define new directions in the field, start new collaborations between U.S. and Japanese researchers and reinforce the existing ones. The exchange of ideas and data with Japanese experts in this field will enable U.S. participants to advance their own work, and will set the stage for future collaborative projects. Seminar organizers have made a special effort to involve graduate students and postdoctoral researchers. The proceedings of the meeting will be made available on the World Wide Web. ***
