Doubly quantized vortices were topologically imprinted in /F=1> 23Na condensates, and their time evolution was observed using a tomographic imaging technique. The decay into two singly quantized vortices was characterized and attributed to dynamical instability. The time scale of the splitting process was found to be longer at higher atom density.
双量子化涡旋被拓扑印刻在/F = 1> 23Na凝聚体中，并使用断层成像技术观察其时间演化。其衰变为两个单量子化涡旋的过程得到了表征，并归因于动力学不稳定性。发现分裂过程的时间尺度在更高的原子密度下更长。
