ABSTRACT:Proposal No: 0508346Title: MICROSCOPIC TRAPS FOR ELECTRONS IN VACUUM PI: Marija DrindicInst: University of Pennsylvania The objective of this NSF NER proposal is to build the first microscopic traps for cold (low-energy) electrons in vacuum and to demonstrate the trapping, detection, and manipulation of single electrons at small scales above surfaces in vacuum. The intellectual merit of this proposal is in developing the technologies for electron trapping, detection and manipulation on small scales in vacuum. In realizing these traps, it will be studied how the electrons interact with nearby surfaces at nanometer and micrometer length-scales, and how the electron motion can be detected and controlled near microfabricated wires. The broad impact of the proposed research is that it will present the first realization of electron "quantum dots" or "artificial atoms" in vacuum. An electron in a microtrap resembles a hydrogen atom; the hydrogen nucleus will be "replaced" in the proposed case by the electrodes of the microtrap. Control of electrons on microscopic scales is expected to open up new possibilities at the interface of atomic and condensed matter physics including integrated electronic circuits in vacuum, single and coupled quantum dots in vacuum and possible implementation of quantum computers. The PI is actively supporting the research of undergraduates, and one undergraduate will be involved in the proposed exploratory project.

摘要：提案编号：0508346TITLE：真空pi中电子的微观陷阱：Marija drindicinst：宾夕法尼亚大学：该NSF NER建议的目标是建立第一个微型陷阱的微观陷阱，以使其在寒冷（低启示）中以真空的范围和范围进行库，并估计陷阱，并范围内的量表，并以较小的范围，并构建陷阱，并构建陷阱的量表 真空。该提议的智力优点在于在真空中的小尺度上开发电子捕获，检测和操纵的技术。 在实现这些陷阱时，将研究电子如何在纳米和微米长度尺度上与附近的表面相互作用，以及如何在微制造线附近检测和控制电子运动。拟议的研究的广泛影响是，它将介绍真空中电子“量子点”或“人造原子”的首次实现。微框中的电子类似于氢原子。在拟议的情况下，氢核将被微框的电极“替换”。 预计对微观量表上电子的控制有望在原子和凝结物理学的界面上打开新的可能性，包括真空中的真空，单和耦合量子点中的集成电子电路以及量子计算机的可能实现。 PI正在积极支持本科生的研究，一位本科生将参与拟议的探索项目。
