论文摘要
我们提出了一种在相互作用的一维玻璃流体中创建运动，稳健的分散冲击波的方案。流体是通过相位印记以移动状态制备的，并将其发送到盒子陷阱的墙壁上。我们证明，如此形成的冲击波在几个时期振荡，并且对热波动是可靠的。我们表明，从弱相互作用到强相互作用的整个原子相互作用强度的整个光谱中，这种大幅度动力学是通用的，并且它完全由流体内部的声速完全控制。我们的工作提供了对多体制制度的分散震动波范式的概括。我们提出的冲击波可以实现超速原子实验。
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.
