Nonlinear atom optics of Bose-Einstein condensates in optical lattices

当一种新的物质状态--玻色-爱因斯坦凝聚态--被困在由光产生的周期性势中时，它形成了一个独特的、可重新配置的纳米尺度系统，对它的性质具有前所未有的控制。它的行为范围从量子到经典，从线性到非线性，从连续到离散。本计画旨在发展光学晶格中BEC的非线性定域、输运与激发的理论。它的结果将提供一个重要的评估的可行性，拟议使用的BEC在量子计算，信息存储，精密测量和纳米技术的光学晶格。

When a new state of matter - Bose-Einstein condensate - is trapped in a periodic potential created by light, it forms a unique, reconfigurable nano-scale system with unprecedented control over its properties. Its behaviour ranges from quantum to classical, from linear to nonlinear, and from continuous to discrete. This project aims to develop a theory for the nonlinear localization, transport, and excitation of BEC in the optical lattices. Its outcome will provide an important assessment of the feasibility of the proposed use of the BEC in optical lattices in quantum computing, information storage, precision measurements, and nanotechnology.
