摘要:

本文报道了在各向异性固态环境中,利用磁场控制氢类似物的量子混沌动力学。利用能级统计方法对系统动力学的混沌性进行了量化。我们分析了杂质能级统计分布与磁场的关系,发现在泊松极限和维格纳极限之间存在一个平滑的过渡,即从正则泊松到完全混沌的维格纳动力学之间的过渡。证明了晶体场各向异性对量子混沌动力学的影响,这种影响表现在不同场取向下规则性和混沌之间的特征转变。

英文摘要:

We report magnetic field control of the quantum chaotic dynamics of hydrogen analogues in an anisotropic solid state environment. The chaoticity of the system dynamics was quantified by means of energy level statistics. We analyzed the magnetic field dependence of the statistical distribution of the impurity energy levels and found a smooth transition between the Poisson limit and the Wigner limit, i.e. transition between regular Poisson and fully chaotic Wigner dynamics. Effect of the crystal field anisotropy on the quantum chaotic dynamics, which manifests itself in characteristic transitions between regularity and chaos for different field orientations, was demonstrated.
