The classical and quantum irregular spin dynamics of atomic spinor Bose-Einstein condensates in an optical lattice, where light-induced and static magnetic dipole-dipole interactions originate the interplay of the condensate at each site, are investigated. Classical-quantum correspondence in the large-spin limit is studied. Quantum chaotic features are studied through analysis of the irregular spectrum and time evolution of the Shannon entropy of wave packets. We show how the optical lattice strength influences the system dynamics, and is responsible for a transition from regular to irregular bahavior.
研究了光晶格中原子自旋玻色-爱因斯坦凝聚体的经典和量子不规则自旋动力学,其中光诱导和静态磁偶极-偶极相互作用引发了每个格点处凝聚体的相互作用。研究了大自旋极限下的经典-量子对应关系。通过分析不规则谱和波包香农熵的时间演化来研究量子混沌特征。我们展示了光光晶格强度如何影响系统动力学,并导致从规则行为到不规则行为的转变。
