光晶格中热原子的混沌动力学
Chaotic dynamics of thermal atoms in labyrinths created by optical lattices
摘要：
研究了非平凡几何结构光晶格中非相互作用热原子的动力学行为。晶格将产生两个相反的传播模式与抛物柱面对称性，我们集中在准保守的红色失谐远共振制度。该系统表现出准周期和混沌行为，其概率可以通过改变光束的强度来控制。轨迹的谱密度被用作混沌签名。对访问多个势阱的混沌轨迹的持久时间的分析揭示了一个长尾分布。
英文摘要：
We study the dynamics of non interacting thermal atoms embedded in structured optical lattices with non trivial geometry. The lattice would be generated by two counter propagating modes with parabolic cylindrical symmetry and we concentrate on the quasi conservative red detuned far-off-resonance regime. The system exhibits quasi periodic and chaotic behaviors whose probability can be controlled by varying the intensity of the beams. The spectral density of the trajectories is used as a chaos signature. An analysis of permanency times for chaotic trajectories that visit more than one potential well reveals a distribution with a long tail.
