我们强调,宏观崩溃的偶极玻色-爱因斯坦凝聚在一个煎饼形的陷阱发生通过局部密度波动,而不是通过一个全球性的崩溃的陷阱中心。这一假设得到了最近在铬冷凝物中进行的实验的支持。
We emphasize that the macroscopic collapse of a dipolar Bose-Einstein condensate in a pancake-shaped trap occurs through local density fluctuations, rather than through a global collapse to the trap center. This hypothesis is supported by a recent experiment in a chromium condensate.
