论文摘要
目前的工作报告了光学晶格中相互作用玻色子的秩序，混乱和复杂性的动态度量。我们报告了放松状态和淬火动态的结果。我们的主要观察结果是：（1）晶格深度可以作为订单订单参数。 （2）可以将超丝向Mott绝缘体转变视为“订单disorder”过渡。我们的主要动机是找到该系统在淬火过程中如何自行组织，以及如何优化复杂性。我们发现，秩序和无序的动态度量比熵测量更灵敏。我们专门计算时间演化期间不同阶段的进入的时间尺度和退出。最初，该系统表现出崩溃的复兴趋势，但是逐渐失去了其转向超流动阶段的能力，并最终定居于Mott绝缘体阶段。
The present work reports on the dynamical measures of order, disorder and complexity for the interacting bosons in optical lattice. We report results both for the relaxed state as well as quench dynamics. Our key observations are: (1) Lattice depth can be taken as order-disorder parameter. (2) The superfluid to Mott insulator transition can be treated as `order-disorder' transition. Our main motivation is to find how the system organize by itself during quench and how it optimizes the complexity. We find dynamical measures of order and disorder are more sensitive tool than entropy measures. We specifically calculate the time scale of entry and exit of different phases during time evolution. Initially the system exhibits collapse revival trend, however gradually looses its ability to turn back to superfluid phase and finally Settle to Mott insulator phase.
