论文摘要
本文比较了跨不同物理理论的船尾grach实验的治疗方法，从而在经典迪拉克场理论的背景下进行了对电子自旋测量的新分析。将电子建模为经典的刚体或点粒子，我们可以解释为什么总是在检测器上的一个位置找到整个电子（唯一性），但是我们无法解释为什么只有两个位置找到了电子（离散性）。使用非权利主义或相对论量子力学，我们可以解释唯一性和离散性。转向更基本的物理学，这两个特征都可以在迪拉克领域的量子理论中解释。在狄拉克场的经典理论中，电子的旋转电荷可以分成两个部分，每个部分都在不同位置击中检测器。在这种经典背景下，我们可以解释电子自旋的特征，该特征通常被描述为独特的量子（离散性），但是我们无法解释其他任何其他理论（独特性）中可以解释的特征。
This article compares treatments of the Stern-Gerlach experiment across different physical theories, building up to a novel analysis of electron spin measurement in the context of classical Dirac field theory. Modeling the electron as a classical rigid body or point particle, we can explain why the entire electron is always found at just one location on the detector (uniqueness) but we cannot explain why there are only two locations where the electron is ever found (discreteness). Using non-relativistic or relativistic quantum mechanics, we can explain both uniqueness and discreteness. Moving to more fundamental physics, both features can be explained within a quantum theory of the Dirac field. In a classical theory of the Dirac field, the rotating charge of the electron can split into two pieces that each hit the detector at a different location. In this classical context, we can explain a feature of electron spin that is often described as distinctively quantum (discreteness) but we cannot explain another feature that could be explained within any of the other theories (uniqueness).
