9731756格莱兹曼研究将对受限相互作用电子系统中的关联电子传输理论进行研究，目的是阐明介观涨落的作用。工作将集中在量子点中的电容波动，双点器件中的介观波动，连接到超导引线上的正常金属颗粒中的介观波动，以及通过垂直隧道进入GaAs异质结实现的2D-3D耦合电子系统中的多体效应和介观波动。首席研究人员计划使用各种理论技术来研究这些系统中的介观涨落，这些方法包括玻色化方法、有效作用方法、重整化群方法以及图解技术。这项理论研究涉及理解电子在电子设备类结构中传输的量子力学过程和现象，这些结构是在原子和宏观之间的长度尺度上构建的。这项工作将对现有实验的解释和新实验的设计产生直接影响，这些实验旨在阐明介观器件中的电子传输物理。在介观和较小长度尺度上对这些现象的研究有望深刻地影响下个世纪新兴的电子设备技术。***

9731756 Glazman Research will be conducted on the theory of correlated electron transport in confined interacting electron systems with an aim to elucidate the role of mesoscopic fluctuations. Work will focus on capacitance fluctuations in quantum dots, mesoscopic fluctuations in double-dot devices, mesoscopic fluctuations in a normal metal grain connected to superconducting leads, and on many body effects and mesoscopic fluctuations in coupled 2D-3D electronic systems that may be realized by vertical tunneling into GaAs heterostructures. The principal investigator plans an analytic approach using various theoretical techniques to investigate mesoscopic fluctuations in these systems; these include methods of bosonization, effective action, renormalization group, as well as diagrammatic techniques. %%% This theoretical research involves understanding quantum mechanical processes and phenomena surrounding the transport of electrons in electronic device-like structures that are constructed on length scales between the atomic and the macroscopic. This work will have immediate impact on the interpretation of existing, and design of new, experiments designed to elucidate the physics of electron transport in mesoscopic devices. The study of these phenomena on mesoscopic and smaller length scales is expected to profoundly influence emerging electronic device technologies of the next century. ***
