Nonintegrable Phases and Nonlocality in Physics

本项目涉及理论考虑 关于“几何”相（Berry相）， 量子系统的状态改变，如果一个封闭的路径被跟踪， 系统的哈密顿量的参数空间。 过去两三年来，这一直是一个活跃的领域。 这个项目将试图研究 贝里相位电磁相位引力相位 来研究相互作用系统的情况。 这项理论工作可能会导致进一步的实验 试验. 由于相位不同的量子干涉效应- 在某些情况下，实际应用，这是可能的。 这种应用最终可能由此产生 工作，但不能预见立即应用。

This project addresses theoretical considerations regarding a "geometrical" phase (Berry's phase) by which the state of a quantum system changes if a closed path is traced in the space of parameters of the Hamiltonians of the system. This has been an active area for the past two or three years. This project will attempt to investigate the relativity between Berry's phase and electromagnetic and gravitational phases and to study the case of interacting systems. This theoretical work could lead to further experimental tests. Since quantum interference effects from phase differ- ences have, in some cases, practical application, it is pos- sible that such application could eventually result from this work, but no immediate applications can be foreseen.
