强电场和磁场中电子运动轨道的混沌现象分析——半经典闭合轨道理论

电场和磁场在原子物理的发展中占有非常重要的地位。当电子在较弱的电场和磁场中运动时，其运动轨迹比较清晰。但是，当电场和磁场很强时，电子的运动轨道开始分岔，运动出现混沌。利用半经典闭合轨道理论，对电子在强电场和磁场中的运动轨道的混沌现象进行了分析，该理论具有物理图象清晰、应用范围广的优点。同时，应用该理论还可以对原子谱的混沌现象进行分析。

Analyzing the chaotic phenomena of the classical trajectories of an electron in strong electric and magnetic fields --Semiclassical closed orbit theory

The electric and magnetic fields have great influence on the development of the atomic physics. When an electron moves in the weak electric and magnetic fields,its trajectory is very clear. But when the external fields are very strong, the trajectory of an electron begins to bifurcate, thus chaos appears. Using semiclassical closed orbit theory, we analyze the chaotic phenomena of the classical trajectories of an electron in strong electric and magnetic fields. This theory has the advantage of clear picture and wide use. And at the same time, we can use this theory to study the chaotic phenomena of the atomic spectra in strong external fields.
