摘要：

研究了在光箱阱的均匀势场中制备的原子吸引玻色-爱因斯坦凝聚体的坍缩。我们的崩溃和崩溃动力学的临界点，观察普遍的行为与理论预期一致。最重要的是，我们观察到了一个明显的违反直觉的弱坍缩的实验特征，即使系统更不稳定可以导致更小的粒子损失。我们通过实验确定了弱坍缩原子损失的标度律，为非线性波现象的一般理论提供了基准。

英文摘要：

We study the collapse of an attractive atomic Bose-Einstein condensate prepared in the uniform potential of an optical-box trap. We characterise the critical point for collapse and the collapse dynamics, observing universal behaviour in agreement with theoretical expectations. Most importantly, we observe a clear experimental signature of the counterintuitive weak collapse, namely that making the system more unstable can result in a smaller particle loss. We experimentally determine the scaling laws that govern the weak-collapse atom loss, providing a benchmark for the general theories of nonlinear wave phenomena.
