我们提出了一种在相互作用的一维玻色流体中产生运动的、健壮的色散激波的方案。流体通过相压印在移动状态下制备，并被送到盒式疏水器的壁上。我们证明了这样形成的激波可以振荡几个周期，并且对热涨落具有很强的抵抗力。我们发现，这种大振幅动力学在整个原子间相互作用强度谱范围内都是普遍的，从弱到强相互作用，并且它完全由流体中的声速控制。我们的工作将色散激波范式推广到多体系统。我们提出的冲击波对于超冷原子实验来说是触手可及的。
We propose a protocol for creating moving, robust dispersive shock waves in interacting one-dimensional Bose fluids. The fluid is prepared in a moving state by phase imprinting and sent against the walls of a box trap. We demonstrate that the thus formed shock wave oscillates for several periods and is robust against thermal fluctuations. We show that this large amplitude dynamics is universal across the whole spectrum of the interatomic interaction strength, from weak to strong interactions, and it is fully controlled by the sound velocity inside the fluid. Our work provides a generalization of the dispersive-shock-wave paradigm to the many-body regime. The shock waves we propose are within reach for ultracold atom experiments.
