克莱因的幻觉

Klein's Paradox

A. Bounames, L. Chetouani

摘要:

本文求解了自旋为1/2的粒子在标量光滑势作用下的一维Feshbach-Villars方程。用超几何函数给出了八分量波函数,并通过极限方法导出了阶跃势的波函数。这些波函数被用来检验由Feshbach-Villars变换导出的边界条件的有效性。从电荷密度的边界条件预测了电子对的产生。

英文摘要:

We solve the one dimensional Feshbach-Villars equation for spin-1/2 particle subjected to a scalar smooth potential. The eight component wave function is given in terms of the hypergeometric functions and via a limiting procedure, the wave functions of the step potential are deduced. These wave functions are used to test the validity of the boundary conditions deduced from the Feshbach-Villars transformation. The creation of pairs is predicted from the boundary condition of the charge density.
