9708499 Langreth The work of this senior and distinguished PI contains several related components. One of them is a density functional theory of long-range interaction between microscopic and mesoscopic bodies. Another looks at a theory of electronic dissipation, non-adiabatic charge transfer and potentials and rates for atoms and molecular species moving and reacting at a solid surface. A third component is an initial foray into the theory of transport in quantum dots using techniques previously developed by the PI for non-adiabatic charge transfer. %%% The work of this senior and distinguished PI is related to the properties of metals and insulators at a surface. The work explores the new physical phenomena which are seen as an electron, an atom or a molecular specie moves near a surface. These include very subtle, long range and technologically important questions of forces between small bodies and between a small grain and a surface. They include complex questions of charge transfer, when does it happen and how. Finally there are attempts to understand transport in very small metallic grains. ***

9708499 Langreth这位高级和杰出的PI的工作包含了几个相关的组件。 其中之一是微观和介观体之间远程相互作用的密度功能理论。 另一个研究电子耗散，非绝热电荷转移以及原子和分子物种在固体表面移动和反应的电势和速率的理论。 第三个组成部分是使用PI先前开发的非绝热电荷转移的技术，对量子点中的运输理论进行初始探索。 %% %%该高级和杰出的PI的工作与表面上的金属和绝缘体的性质有关。 这项工作探讨了新的物理现象，该现象被视为电子，原子或分子规范在表面附近移动。 这些包括非常微妙的，远距离和技术上重要的力问题​​，在小物体之间以及小谷物和表面之间的力量。 它们包括复杂的收费转移问题，何时发生以及如何发生。 最后，试图了解非常小的金属谷物的运输。 ***
