标题： Density, phase and coherence properties of a low dimensional Bose-Einstein systems moving in a disordered potential

摘要： 我们展示了对无序一维玻色-爱因斯坦凝聚体在位置和动量空间动力学的详细数值研究。 我们特别关注非线性和无序同时影响凝聚体时间传播以及物质波各部分之间可能干涉的区域。 我们报告了传播凝聚体在空间扩展行为与局域化行为之间的振荡现象，这种振荡随着非线性增强而减弱。 我们还报告了物质波相位涨落和相干性的有趣行为。 我们还简要比较了一维凝聚体与二维凝聚体的这些行为。 我们提到我们的结果与安德森局域化相关实验的相关性，并指出未来实验的可能性。 显示英文摘要

摘要： We present a detailed numerical study of the dynamics of a disordered one-dimensional Bose-Einstein condensates in position and momentum space. We particularly focus on the region where non-linearity and disorder simultaneously effect the time propagation of the condensate as well as the possible interference between various parts of the matter wave. We report oscillation between spatially extended and localized behavior for the propagating condensate which dies down with increasing non-linearity. We also report intriguing behavior of the phase fluctuation and the coherence properties of the matter wave. We also briefly compare these behavior with that of a two-dimensional condensate. We mention the relevance of our results to the related experiments on Anderson localization and indicate the possibility of future experiments
