论文摘要
我们在实验和理论上探讨了涡旋线在极性磁相的创建和时间演变的创建和时间演变，这是一个陷阱的旋转1 $^{87} $ rb bose-einstein冷凝物。相位刻板涡流的过程，将其衰减成一对单数旋转涡流以及磁性阶段的快速交换产生了一对三维，单一单一单一的单一单一量化的涡流，与核心区域与铁磁相中的原子填充。原子相互作用指导了随后的涡流动力学，导致核心结构表明单一量化的涡旋腐烂成半量子涡流。
We experimentally and theoretically explore the creation and time evolution of vortex lines in the polar magnetic phase of a trapped spin-1 $^{87}$Rb Bose-Einstein condensate. A process of phase-imprinting a nonsingular vortex, its decay into a pair of singular spinor vortices, and a rapid exchange of magnetic phases creates a pair of three-dimensional, singular singly-quantized vortex lines with core regions that are filled with atoms in the ferromagnetic phase. Atomic interactions guide the subsequent vortex dynamics, leading to core structures that suggest the decay of the singly-quantized vortices into half-quantum vortices.
