论文摘要
我们提供了一个分析模型，以在双裂光学晶格下构建玻色子冷凝水的指数定位。这种本地化被称为安德森本地化。参与比研究了定位程度，以识别安德森本地化的激光参数域。证明了本地化的指数性质，我们还确定了定位长度。观察到了随时间的安置凝结物的隧道，并报告了安德森本地化的复兴现象。对于更高的激光强度，注意到安德森本地化的放缓。我们还研究了安德森定位期间冷凝物的动力学和结构稳定性，这表明激光功率和时间实例的首选值在存在噪声的情况下会遇到最小的平均差异。
We provide an analytical model to fabricate an exponential localization of a Bose-Einstein condensate under bichromatic optical lattice. Such localization is famously known as Anderson localization. The degree of localization is investigated by the Participation Ratio to recognize the laser parameter domain for Anderson localization. The exponential nature of the localization is proved, where we also identify the Localization Length. The tunneling of Anderson-localized condensate with time is observed, and the revival phenomenon of Anderson localization is reported. Slowing down of Anderson localization is noticed for higher laser intensity. We also study the dynamical and structural stability of the condensate during Anderson localization, which suggests the preferred values of laser power and time instance to encounter minimal mean difference in the presence of noise.
