We present numerical results for three-dimensional (3D) solitons with symmetries of the semi-vortex (SV) and mixed-mode (MM) types, which can be created in spinor Bose-Einstein condensates of Rydberg atoms under the action of the spin-orbit coupling (SOC). By means of systematic numerical computations, we demonstrate that the interplay of SOC and long-range spherically symmetric Rydberg interactions stabilize the 3D solitons, improving their resistance to collapse. We find how the stability range depends on the strengths of the SOC and Rydberg interactions and the soft-core atomic radius.
我们给出了具有半涡旋（SV）和混合模式（MM）对称性的三维（3D）孤子的数值结果，这些孤子可以在自旋 - 轨道耦合（SOC）作用下的里德堡原子自旋玻色 - 爱因斯坦凝聚体中产生。通过系统的数值计算，我们证明了SOC和长程球对称里德堡相互作用的相互作用使3D孤子稳定，提高了它们的抗坍缩能力。我们发现稳定性范围如何取决于SOC和里德堡相互作用的强度以及软核原子半径。
