Electron Correlations and Properties of Metals and Insulators

这个理论项目由几个相关的主题组成。其中之一是微观和介观物体之间远距离和短程相互作用的密度泛函理论。另一种是电子耗散理论，非绝热电荷转移理论，以及原子和分子在固体表面运动和反应的电位和速率理论。第三个组成部分是量子点的输运理论，使用先前为非绝热电荷转移开发的技术。这项工作与表面上的金属和绝缘体的性质有关。它探索新的物理现象，被视为一个电子，一个原子，或一个分子物种靠近一个表面移动。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的、长期的和技术上重要的问题。它们包括电荷转移、耗散和能量转移等复杂问题，以及它们何时发生和如何发生。最后，有人试图理解单电子晶体管中的输运，单电子晶体管由嵌入半导体表面金属层的非常小的人工结构组成。这是一个由许多相关主题组成的理论项目，包括处理小物体（电子，原子，分子）与大物体（表面和量子点）的相互作用。包括与纳米现象和纳米器件相关的基本问题

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.***
