We propose a scheme to investigate vector spatio-temporal soliton pairs via double Rydberg electromagnetically induced transparency (EIT). We show that three dimensional (3D) vector monopole and vortex solitons, with ultralow generation power and ultraslow speed, have been found under three response regions. In particular, these spatio-temporal soliton pairs experience a significant Stern-Gerlach deflection when a gradient magnetic field is applied to the system. The results reported here are useful not only for extending the research realm of nonlinear magneto-optics but also for the application in the detection of microgradient magnetic fields.

冷里德堡气体中矢量时空孤子对的 Stern-Gerlach 偏转

我们提出了一种通过双里德堡电磁感应透明度 (EIT) 研究矢量时空孤子对的方案。我们表明，在三个响应区域下发现了具有超低发电功率和超慢速度的三维 (3D) 矢量单极子和涡旋孤子。特别是，当向系统施加梯度磁场时，这些时空孤子对会经历显着的 Stern-Gerlach 偏转。这里报告的结果不仅有助于扩展非线性磁光的研究领域，而且有助于在微梯度磁场检测中的应用。
