Presently optical-lattice systems holding ultracold-temperature atoms may already be tuned experimentally so that they may behave either classically or quantum mechanically. In this work such systems are studied theoretically. For instance, it will be shown that the very act of monitoring the atoms may cause them to behave classically. The goal is to turn such observations into quantitative methods to analyze and engineer nanoscale devices that operate at the crossover between quantum mechanics and classical mechanics.Research topics from this work are incorporated into both graduate and undergraduate courses and specialist scientists are trained, so that the project will contribute to the development of high-technology workforce. Scientifically, the project should help to build the basis for future nanotechnology.

目前，容纳超低温原子的光学晶格系统可能已经通过实验进行了调整，使它们可以表现出经典或量子力学的行为。在这项工作中，这样的系统进行了理论研究。例如，它将表明，监测原子的行为可能会导致它们的行为经典。本项目的目标是将这些观测转化为定量方法，以分析和设计在量子力学和经典力学交叉点运行的纳米级器件。本项目的研究课题被纳入研究生和本科生课程，并培养专业科学家，从而为高科技人才的发展做出贡献。从科学的角度来看，该项目应该有助于为未来的纳米技术奠定基础。
