简介：我们在场对为在两倍井的ultracold波色子的物理政体的彻底的描述，与专辑，注意付钱到宏观的重叠(MS)。我们使用多达八个单个粒子模式的Lipkin-Meshkov-GlickHamiltonian的归纳学习这些MS，解决有数字准确diagonalization和高顺序的不安理论的联合的Hamiltonian。MS在左、正确的潜在的井之间；有同时位于井并且在仅仅二个模式的所有原子的极端情况是著名中午状态，但是我们的途径包含更一般的MS。更单个的粒子模式的使用把维数带进这个问题，允许我们将难限制放在通常在文学对待的原来的二模式的LMG模型的使用上，并且也介绍混合Josephson-Fock政体。更高的模式与不同尖性质介绍自由和MS状态的尖度。

简介：平淡的波浪重叠途径不能在一块协调的声学的地的重建和预言被使用，因为分开单个来源产生的压力是不可能的。根据协调的声学的地的重叠理论，一个新奇方法基于联合波浪重叠途径被开发重建并且由造匹配在全息图表面和来源之间的矩阵的联合压力预言协调的声学的地。方法能重建个人的表面的声学的信息采购原料，并且预言也从每来源和全部的协调的声学的地罐头散发的声学的地自发地被计算是可能的。试验性、数字的模拟结果证明这个方法能有效地解决holographic重建和协调的声学的地的预言，它能也被用作一种协调的声学的地分离技术。这个新奇方法上的学习扩大声学的雷射摄影术技术的应用程序范围。
