A. D. Alhaidari

摘要:

本文给出了库仑场中质量随位置变化的带电粒子的狄拉克方程的精确解。旋量的有效质量有一个相对论分量,它与康普顿波长的平方成正比,变化为1/r。该模型可作为场论中紫外发散重正化的一种工具。给出了离散的能谱和旋量波函数。

英文摘要:

We obtain exact solution of the Dirac equation for a charged particle with position-dependent mass in the Coulomb field. The effective mass of the spinor has a relativistic component which is proportional to the square of the Compton wavelength and varies as 1/r. It is suggested that this model could be used as a tool in the renormalization of ultraviolet divergences in field theory. The discrete energy spectrum and spinor wave-function are obtained explicitly.
