Rydberg-Induced Topological Solitons in Three-Dimensional Rotation Spin-Orbit-Coupled Bose-Einstein Condensates

We present a novel approach for generating stable three-dimensional (3D) spatiotemporal solitons (SSs) within a rotating Bose-Einstein condensate, incorporating spin-orbit coupling (SOC), a weakly anharmonic potential and cold Rydberg atoms. This intricate system facilitates the emergence of quasi-stable 3D SSs with topological charges |m| <= 3 in two spinor components, potentially exhibiting diverse spatial configurations. Our findings reveal that the Rydberg long-range interaction, spin-orbit coupling, and rotational angular frequency exert significant influence on the domains of existence and stability of these solitons. Notably, the Rydberg interaction contributes to a reduction in the norm of topological solitons, while the SOC plays a key role in stabilizing the SSs with finite topological charges. This research of SSs exhibits potential applications in precision measurement, quantum information processing, and other advanced technologies.
