驱动-耗散原子阵列中的涌现极限循环、混沌与双稳态

我们分析次波长周期原子阵列在自由空间中的驱动-耗散动力学，其中原子通过光致偶极-偶极相互作用相互作用。我们发现， Depending on system parameters, underlying mean-field model 在滞后时段允许四种不同的动力学类型：单一单稳态解、双稳态（存在两个稳态解）、极限循环和混沌动力学。我们提供实现不同解所需参数条件的 thermodynamic limit。 In this limit, only monostable or bistable regime can be accessed for parameter values accessible via light-induced dipole-dipole interactions. For finite size periodic arrays, however, we find that the mean-field dynamics of the many-body system also exhibit limit cycles and chaotic behavior. Notably, the emergence of chaotic dynamics does not rely on the randomness of an external control parameter but arises solely due to the interplay of coherent drive and dissipation.
