论文摘要
我们分析了有关在磁场和标量电势存在下宇宙字符串时空中带电粒子的``相对论量子动力学的结果''的论文的结果。我们表明，作者没有获得特征值方程的频谱，而是一个特征值，用于模型参数之间的特定关系。特别是，作者猜想的允许的回旋频率的存在仅仅是用于获得径向特征值方程的精确溶液的截断条件的伪像。
We analyze the results of a paper on ``Relativistic quantum dynamics of a charged particle in cosmic string spacetime in the presence of magnetic field and scalar potential''. We show that the authors did not obtain the spectrum of the eigenvalue equation but only one eigenvalue for a specific relationship between model parameters. In particular, the existence of allowed cyclotron frequencies conjectured by the authors is a mere artifact of the truncation condition used to obtain exact solutions to the radial eigenvalue equation.
