How to be a Relativistic Spacetime State Realist

According to spacetime state realism (SSR), the fundamental ontology of a quantum mechanical world consists of a state-valued field evolving in four-dimensional spacetime. One chief advantage it claims over rival wave-function realist views is its natural compatibility with relativistic quantum field theory (QFT). I argue that the original density operator formulation of SSR cannot be extended to QFTs where the local observables form type III von Neumann algebras. Instead, I propose a new formulation of SSR in terms of a presheaf of local state spaces dual to the net of local observables studied by algebraic QFT. 1. Introduction2.

如何成为一个相对论时空状态现实主义者

根据时空状态实在论 (SSR),量子力学世界的基本本体由在四维时空中演化的状态值场组成。它声称优于竞争对手的波函数实在论观点的一个主要优势是它与相对论量子场论 (QFT) 的天然兼容性。我认为 SSR 的原始密度算子公式不能扩展到 QFT,其中局部可观察量形成 III 型冯诺依曼代数。相反,我根据与代数 QFT 研究的局部可观察量网络对偶的局部状态空间的预层提出了 SSR 的新公式。1. 介绍 2. 量子场论中的时空状态实在论 2.1.等价论 3.纠缠和第三类性质 3.1。禁止引理 13.2。No-Go Lemma 24. 量子场论的状态空间公理 4.1。修订等价论文5。讨论 介绍量子场论中的时空状态实在论 2.1.等价论文 等价论文 纠缠和第三类性质 3.1.禁止引理 13.2。No-Go Lemma 2 No-Go Lemma 1 No-Go Lemma 2 量子场论的状态空间公理 4.1。修订等价论文 修订等价论文 讨论
