It has been widely thought that the wave function describes a real, physical field in a realist interpretation of quantum mechanics. In this paper, I present a new analysis of the field ontology for the wave function. First, I argue that the non-existence of self-interactions for a quantum system such as an electron poses a puzzle for the field ontologists. If the wave function represents a physical field, then it seems odd that there are (electromagnetic and gravitational) interactions between the fields of two electrons but no interactions between two parts of the field of an electron. Next, I argue that the three solutions a field ontologist may provide are not fully satisfactory. Finally, I propose a solution of this puzzle that leads to a particle ontological interpretation of the wave function.

领域本体论者的谜题

人们普遍认为，波函数在量子力学的现实主义解释中描述了一个真实的物理场。在本文中，我对波函数的场本体进行了新的分析。首先，我认为量子系统（如电子）不存在自相互作用给领域本体论者带来了一个难题。如果波函数代表一个物理场，那么两个电子的场之间存在（电磁和引力）相互作用，而一个电子场的两个部分之间没有相互作用，这似乎很奇怪。接下来，我认为领域本体论者可能提供的三种解决方案并不完全令人满意。最后，我提出了这个难题的解决方案，它导致对波函数的粒子本体论解释。
