摘要：

我们表明，喷流发射从玻色凝聚与周期性驱动的相互作用，又名。“玻色烟花”，包含了凝聚波函数的基本信息，这是很难获得使用标准的检测方法。我们用两个例子来说明基本的物理原理。当凝结体从外部势或旋涡中获得相位图案时，射流在它们的相关性中显示出新的子结构，例如振荡或螺旋。通过理论，数值模拟和实验的比较，我们展示了如何可以定量提取的相位和螺旋度的冷凝物的排放模式。我们的工作证明了喷流发射和底层量子系统之间的密切联系，这与粒子物理学中最近强调的喷流子结构有关。

英文摘要：

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.
