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这位资深和杰出的PI的工作包含几个相关的组成部分。 其中之一是微观和介观物体之间长程相互作用的密度泛函理论。 另一个着眼于电子耗散理论，非绝热电荷转移和原子和分子物种移动和在固体表面反应的潜力和速率。 第三个组成部分是使用PI先前开发的非绝热电荷转移技术对量子点传输理论的初步尝试。 这位资深而杰出的PI的工作与表面的金属和绝缘体的性质有关。 这项工作探索了新的物理现象，这些现象被视为电子，原子或分子物种在表面附近移动。 这些问题包括小物体之间以及小颗粒和表面之间的力的非常微妙、长距离和技术上重要的问题。 它们包括电荷转移的复杂问题，何时发生以及如何发生。 最后，有人试图了解非常小的金属颗粒中的输运。 ***
