U.S.-India Collaborative Research: Metastable State Dynamics of Hard Spheres, Award in U.S. and Indian Currency

9615767任务描述：这是一个名为硬球体亚稳态动力学的美国-印度研究合作项目。该项目由佛罗里达大学的James W. duffy和新德里贾瓦哈拉尔尼赫鲁大学的Shankar P. Das指导。研究人员将研究长期存在的描述玻璃形成和玻璃性质的问题。他们的目标是确定造成非常缓慢的动力学的定性机制，并发展定量分析的实用方法。他们将把他们的研究限制在理想的硬球系统，以便利用最近的发展，允许对致密流体和晶体相的动力学进行精确的理论分析，这对任何其他原子或分子系统都是不可用的。这些原型研究将解决一些与玻璃形成及其性质相关的最基本问题。玻璃及其复合材料在新材料的发展中发挥着重要作用，具有广泛的应用前景。范围：此次合作是由两位非常有能力的研究者的研究兴趣驱动的，他们在过去的六年里一直在密切相关的研究上合作。他们为解决重大问题而开发的独特方法具有取得科学突破的巨大潜力。所要求的支助主要用于旅费和每日津贴。参与该计划的博士后和研究生将由各自的机构提供支持。＊＊＊

9615767 Dufty Description: This is a U.S.-India research collaboration entitled Metastable State Dynamics for Hard Spheres. The project is under the direction of James W. Dufty, University of Florida and Shankar P. Das, Jawaharlal Nehru University, New Delhi. The investigators will study the long-standing problem of describing glass formation and the properties of glasses. Their objectives are to identify qualitative mechanisms responsible for very slow dynamics and to develop practical methods for quantitative analysis. They will limit their study to the idealized hard sphere system in order to take advantage of recent developments which permit accurate theoretical analyses of the dynamics in both dense fluid and crystal phases, not available for any other atomic or molecular systems. These prototype studies will address some of the most basic questions relevant to glass formation and their properties. Glasses and related composites play an essential role in the development of new materials in a wide range of applications. Scope: This collaboration is driven by the research interests of two highly competent investigators who have worked together on closely related research for the past six years. The unique approach they have developed for solving a significant problem has excellent potential for scientific breakthrough. The support requested is primarily for travel and per diem. Postdocs and graduate students involved in the program will be supported by their respective institutions. ***
