论文摘要
我们表明，来自带有定期驱动相互作用的BOSE冷凝物的喷射发射，也就是“ Bose Fireworks”，其中包含有关冷凝水波函数的基本信息，使用标准检测方法很难获得。我们用两个例子说明了基础物理学。当冷凝物从外部电势或涡旋中获取相位模式时，喷气机在其相关性中显示出新颖的子结构，例如振荡或螺旋。通过比较理论，数值模拟和实验，我们展示了如何从发射模式中定量提取冷凝物的相位和螺旋。我们的工作证明了射流发射与基础量子系统之间的牢固联系，这对粒子物理学中的射流子结构的最新重视。
We show that jet emission from a Bose condensate with periodically driven interactions, a.k.a. "Bose fireworks", contains essential information on the condensate wavefunction, which is difficult to obtain using standard detection methods. We illustrate the underlying physics with two examples. When condensates acquire phase patterns from external potentials or from vortices, the jets display novel sub-structure, such as oscillations or spirals, in their correlations. Through a comparison of theory, numerical simulations and experiments, we show how one can quantitatively extract the phase and the helicity of a condensate from the emission pattern. Our work demonstrating the strong link between jet emission and the underlying quantum system, bears on the recent emphasis on jet sub-structure in particle physics.
