项目摘要

Professor R. Stephen Berry at the Department of Chemistry, University of Chicago, is supported by a grant from the Theoretical and Computational Chemistry Program at NSF for theoretical studies of atoms and clusters. The work supported by this grant falls into three groups of related topics: (1) second-order phase transitions as modeled by clusters; (2) the relationship between the topography of potential energy surfaces and the formation of special structures, as in protein folding; and (3) angular electron correlation in atoms. A connecting theme is that the theoretical studies are directly related to experimental studies. Clusters are special and unique forms of matter that lie between isolated atoms and molecules at one extreme and the solid state at the other extreme. While the properties of clusters are important for their own sake, they are also important because they bridge these two extremes. A long term objective of the cluster work that this grant supports is to understand how cluster properties determine, and ultimately merge with, bulk properties. The supported work integrates analytic theory, computation, and computer simulation into an approach with three primary goals: (1) deepening the understanding of commonplace properties of matter; (2) identifying new properties specific to matter at the scale of clusters and nanoscale particles; and (3) stimulating new experiments.

R教授斯蒂芬·贝瑞在化学系，大学芝加哥，由理论和计算科学基金会资助。美国国家科学基金会的化学项目，用于原子和团簇的理论研究。这项资助所支持的工作分为三组相关的福尔斯主题：（1）团簇模拟的二阶相变;（2）势能面的形貌与特殊结构的形成，如蛋白质折叠;（3）原子中的电子角相关一个相关的主题是，理论研究与实验研究直接相关。星系团是一种特殊而独特的物质形式，一端是原子和分子，另一端是固态极端。虽然团簇的性质对它们自身的性质很重要，它们也很重要，因为它们是这两个极端的桥梁。一该补助金支持的集群工作的长期目标是了解群集属性如何决定，并最终与之合并，整体性能所支持的工作整合了分析理论，计算和计算机模拟的方法与三个主要的目标：（1）加深对普通属性的理解，（2）确定物质在尺度上的新特性。团簇和纳米颗粒;（3）激发新的实验。
