摘要:

本文引入了自旋为1的粒子作为zitterbewegung的激发态的相对论量子机械波方程,并证明了它与2+1维Proca理论是一致的。同时,我们发现在静止坐标系下,该方程有两个本征态,分别是粒子态和反粒子态,或负能量本征态和正能量本征态,并且满足$SO(2,1)$自旋代数.作为实际应用,我们导出了在恒定磁场和弯曲时空中方程的精确解。从这些解中,我们通过在超曲面上积分所构造的自旋1粒子流,找到了Noether荷,并讨论了由该荷产生的对。我们还看到,由于Noether荷是由概率粒子流导出的,所以对Noether荷的讨论是理解对产生现象的有用工具。

英文摘要:

In this study, we introduce a relativistic quantum mechanical wave equation of the spin-1 particle as an excited state of the zitterbewegung and show that it is consistent with the 2+1 dimensional Proca theory. At the same time, we see that in the rest frame this equation has two eigenstates, particle and antiparticle states or negative and positive energy eigenstates, respectively, and satisfy $SO(2,1)$ spin algebra. As practical applications, we derive the exact solutions of the equation in the presence of a constant magnetic field and a curved spacetime. From these solutions, we find Noether charge by integrating the constructed spin-1 particle current on hyper surface and discuss pair production from the charge. And, we see that the discussion on \ the Noether charge is useful tool for undersdantding the pair production phenomenon because the charge is derived from a probabilistic particle current.
