Electron Correlations and Properties of Metals and Insulators

9708499 Langreth这位资深而杰出的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远距离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。第三个组成部分是使用PI先前开发的非绝热电荷转移技术对量子点输运理论的初步探索。这个高级和杰出的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的、长期的和技术上重要的问题。它们包括电荷转移、何时发生以及如何发生等复杂问题。最后，有人试图了解非常小的金属颗粒中的输运。＊＊＊

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. ***
