近年来，原子玻色-爱因斯坦凝聚体中的量子化涡旋激发物理已得到广泛的研究。虽然简单涡旋线在实验中相对容易产生、控制和测量，但对涡旋环结构的产生和控制却困难得多。本文提出并探索了一种产生和控制超流涡旋环、涡旋环晶格和涡旋环晶格的方法。利用光学振荡器产生的人工磁场，研究了超流玻色-爱因斯坦凝聚体中的三维涡旋结构。连接的几何形状，我们表明，在这种情况下，这些旋涡结构的存在下，可以推导出从激发剪刀模式的凝聚。
The physics of quantized vortex excitations in atomic Bose-Einstein condensates has been extensively studied in recent years.Although simple vortex lines are relatively easy to create, control, and measure in experiments, it is a lot more difficult to do the same for vortex ring structures.Here we suggest and explore a method for generating and controlling superfluid vortex rings, vortex ring lattices, and other three dimensional vortex structures in toroidally-trapped superfluid Bose--Einstein condensates by using the artificial magnetic field produced by an optical nanofiber.The presence of the fiber also necessitates a multiply-connected geometry and we show that in this situation the presence of these vortex structures can be deduced from exciting the scissors mode of the condensate.
