摘　　要：实现高维光孤子是非线性光学研究中一个长期的目标.本文设计了一个里德伯冷原子与贝塞尔晶格势耦合的系统,发现了一系列稳定的二维空间光孤子簇,包括基极孤子、二级孤子、四级孤子和涡旋孤子.研究表明,光传播系数、非局域非线性系数、贝塞尔晶格常数可以用来调控光孤子的产生、空间分布及演化;在系统参数的调控下,该光孤子簇具备空间稳定性,能够在一定距离内稳定传播.本研究为高维空间光孤子的产生和调控提供了一种新的思路.Realizing stable high-dimensional light solitons is a long-standing goal in the study of nonlinear optical physics.However,in high-dimensional space,the light field will inevitably be distorted due to diffraction.In order to solve the diffraction effect in nonlinear Kerr media and achieve the spatial localization of light fields,we propose a scheme to generate stable two-dimensional(2D)solitons in a cold Rydberg atomic system with a Bessel optical lattice,where a three-level atomic structure,a weak probe laser field,and a strong control field constitute the Rydberg-dressed atomic system.When the local nonlinearity,Bessel potential,and nonlocal .
