How to Justify the Symmetrization Postulate in Quantum Mechanics

The aim of this paper is to reconstruct and correct one argument (known in the literature as the exchange degeneracy argument) in support of the symmetrization postulate in quantum mechanics. I identify the central premise of the argument as a thesis specifying a particular ontic (or epistemic) property of quantum superpositions. The precise form of this thesis depends on some underlying assumptions of a metaphysical character (concerning identifications of objects across possible worlds, or representations de re). I compare the exchange degeneracy argument with alternative formal arguments for the symmetrization postulate, and I discuss the role and meaning of labels in the symmetric/antisymmetric representations of the states of many particles.

如何证明量子力学中的对称化假设

本文的目的是重建和纠正一个论点(在文献中称为交换简并论点)以支持量子力学中的对称化假设。我将论证的中心前提确定为指定量子叠加的特定本体(或认知)属性的论文。这篇论文的精确形式取决于形而上学特征的一些基本假设(关于跨可能世界的对象的识别,或 de re 的表示)。我将交换简并论证与对称化假设的替代形式论证进行了比较,并讨论了标签在许多粒子状态的对称/反对称表示中的作用和意义。
