0093079LangrethThis theoretical project is comprised of several related topics. One of them is density functional theory of both long-range and short-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 the theory of transport in quantum dots using techniques previously developed for non-adiabatic charge transfer. This work is related to the properties of metals and insulators at a surface. It explores the new physical phenomena which are seen as an electron, an atom, or a molecular species 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, dissipation and energy transfer, when do they happen and how. Finally there are attempts to understand transport in single electron transistors, consisting of very small artificial structures embedded in metallic layers on semiconductor surfaces.%%%This is a theoretical project comprised of a number of related topics including ones dealing with the interactions of small objects (electrons, atoms, molecules) with larger ones (surfaces and quantum dots). Included are fundamental issues related to nanoscale phenomena and nanodevices.***

0093079这本理论项目由几个相关主题组成。 其中之一是显微镜和介观体之间远程和短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先前用于非绝热电荷转移的技术中的量子点传输理论。 这项工作与表面上的金属和绝缘体的特性有关。 它探索了新的物理现象，该现象被视为电子，原子或分子物种在表面附近移动。 这些包括非常微妙的，远程和技术上重要的小物体之间以及小谷物和表面之间的力量。 它们包括复杂的电荷转移，耗散和能源转移，何时发生以及如何发生的问题。 最后，试图了解单电子晶体管中的传输，由非常小的人造结构组成，这些结构嵌入了半导体表面上的金属层中。%% %%这是一个理论项目，其中包括许多相关主题，包括与小对象（电子，原子，分子）与较大对象的相互作用的相互作用（surface and surface and surface and duroface and dots）。 其中包括与纳米级现象和纳米版有关的基本问题。***
