A scheme is proposed to generate stable spatiotemporal solitons (STs) in a cold Rydberg atomic system with a Bessel Lattice (BL) potential, by utilizing electromagnetically induced transparency (EIT). We investigate the existence and stability of these three-dimensional (3D) STs supported by BL in nonlocal nonlinear media. The results show that the system can support slow STs with low light intensity. We also find that the BL strength and the degree of nonlocality of the nonlinearity, which can be tuned in the system, can be used to control these STs and their propagation behaviors.

具有贝塞尔光学晶格的冷里德堡原子气体中的时空孤子

提出了一种利用电磁感应透明性（EIT）在具有贝塞尔格子（BL）势的冷Rydberg原子系统中生成稳定的时空孤子（ST）的方案。我们调查在非局部非线性介质中BL支持的这些三维（3D）ST的存在和稳定性。结果表明，该系统可以支持低光强度的慢速ST。我们还发现，可以在系统中调整的BL强度和非线性度的非局部性程度，可以用于控制这些ST及其传播行为。
