简介：作为为量状态转移匹配状况(SPMC)的光谱同等值的示范，我们在限制外部正切磁场经分解并且数字地在Heisenbergchain调查单个磁量子的状态的繁殖。它证明起始的Gaussian波浪包能在对应物地点接近完美地被检索在上更距离如果系统的分散关系近似遇见SPMC。

简介：我们介绍预兆的控制理论进混乱控制的学习并且求婚一。指导基于一个神经网络模型优化预兆的控制算法。Theproposed控制系统在一个未知混乱系统稳定混乱运动到需要的目标轨道上。与存在相比类似的算法，建议控制系统有更快的反应，它因此为混乱系统的稳定要求短得多的时间。Theproposed途径能控制亢奋的混乱，算法简单。控制算法和控制系统的稳定性的集中能被保证。理论上的分析和模拟表明算法的有效性。

简介：为在当前模式的增加变换器的混乱的控制的一个方法被使用一阶的动态反馈控制介绍。反馈部分在系列由一个电阻和一个电容组成。要控制的系统被当作third-ordermodel，然后分离印射模型被使用数据采样方法获得。Byanalysing最大的标准特征值的位置，反馈获得的稳定的范围外面被查明，它的优化也被执行。最后，模拟和实验的结果证实理论分析的正确性和建议工具的有效性。
