我们给出了原子在强静磁场和激光场中的经典和量子力学时间演化的计算机电影。原子电子的共振诱导相对论运动导致环状空间概率密度，称为环原子。我们进一步证明，自旋轨道耦合的快速移动的电子在一个环原子变得显着，修改的时间依赖性的自旋，即使最初对齐平行于静磁场方向。我们还介绍了几部关于自旋分布随相对论量子态位置变化的时间演化的电影。这种空间分辨自旋测量的性质进行了分析。
We present computer movies of the classical and quantum mechanical time evolution for an atom in a strong static magnetic field and a laser field. The resonantly induced relativistic motion of the atomic electron leads to a ring-like spatial probability density called a cycloatom. We further demonstrate that spin-orbit coupling for a fast moving electron in a cycloatom becomes significant, modifying the time-dependence of the spin even if initially aligned parallel to the static magnetic field direction. We also present several movies on time-evolution of the spin-distribution as a function of the position for a relativistic quantum state. The nature of such a space resolved spin measurement is analyzed.
