在弯曲时空中狄拉克理论的非唯一性问题的缺失。自旋-旋转耦合与物理无关

Absence of the non-uniqueness problem of the Dirac theory in a curved spacetime. Spin-rotation coupling is not physically relevant

M. V. Gorbatenko, V. P. Neznamov

摘要:

与Arminjon的陈述相反,在这项工作中,我们再次断言在弯曲和平坦的时空中不存在狄拉克理论的非唯一性问题,并用一些例子来说明这一点。狄拉克哈密顿量在任意的,包括时间相关的,引力场唯一地确定量子力学系统的物理特性,而不管选择的四元组场。直接自旋-旋转耦合发生在四分体的特定选择中,并不表现在系统的最终物理特性中,因此不代表物理相关效应。

英文摘要:

As opposed to Arminjon statements, in this work we again assert the absence of the non-uniqueness problem of the Dirac theory in a curved and flat spacetime and illustrate this with a number of examples. Dirac Hamiltonians in arbitrary, including time-dependent, gravitational fields uniquely determine physical characteristics of quantum-mechanical systems irrespective of the choice of the tetrad fields. Direct spin-rotation coupling that occurs with a certain choice of tetrads does not manifest itself in final physical characteristics of the systems and therefore does not represent a physically relevant effect.
