U.S.-Japan Joint Seminar: Understanding and Conquering Long Time Scales in Computer Simulations

9817720兰道该奖项支持美国科学家参与美国- 1999年8月9日至12日在夏威夷举行的日本计算机模拟中理解和克服长时间尺度研讨会。 共同组织者是格鲁吉亚大学的大卫朗道教授和日本东京首都大学的冈部丰教授。统计物理学中的计算机模拟在物理学的不同领域带来了令人印象深刻的知识增益。 随着并行计算平台的出现，模拟相当大的系统已经成为可能，我们现在可以认真考虑通过使用互补算法来跨越长度尺度的许多数量级的方法。 然而，物理学中存在着许多问题，阻碍物理学发展的不是系统的大小，而是有限的时间尺度。本次研讨会的目的是为了理解在不同系统中发生的长时间尺度问题，并探讨克服这些困难的方法。 研讨会的重点涉及以下主题：1）临界减速-弛豫和动力学; 2）经典模型的集群算法; 3）自旋玻璃和挫折; 4）玻璃和玻璃形成; 5）聚合物和蛋白质; 6）量子模拟方法;和7）纳米系统和磁化反转。 研讨会的组织者作出了特别努力，让年轻的研究人员既参加研讨会，又作为观察员参加。 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。 预计会议记录将发表在《现代物理学杂志》上。“此外，个人论文将在格鲁吉亚大学模拟物理中心提供。***

9817720LandauThis award supports the participation of American scientists in a U.S.-Japan seminar on Understanding and Conquering Long Time Scales in Computer Simulations, to be held in Hawaii from August 9-12, l999. The co-organizers are Professors David Landau at the University of Georgia and Yutaka Okabe at the Tokyo Metropolitan University in Japan. Computer simulations in statistical physics have resulted in impressive gains in knowledge in diverse areas of physics. With the advent of parallel computing platforms, it has become possible to simulate quite large systems and we can now seriously consider ways to span many orders of magnitude in length scale by using complementary algorithms. There are many problems in physics, however, where it is not the size of the system that hinders progress but rather the restricted timescales that can be examined.The goal of this seminar is to focus on understanding the problems with long time scales, which occur in diverse systems, and to examine ways of overcoming these difficulties. The focus of the seminar involves the following topics: 1) critical slowing down - relaxation and dynamics; 2) cluster algorithms for classical models; 3) spin glasses and frustration; 4) glasses and glass formation; 5) polymers and proteins; 6) quantum simulation methods; and 7) nanoscale systems and magnetization reversal. Seminar organizers have made a special effort to involve younger researchers as both participants and observers. 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. It is anticipated that the proceedings will be published in the "Journal of Modern Physics C." In addition, the individual papers will be available at the Center for Simulation Physics at the University of Georgia. ***
