The Fermionic Projector, Entanglement, and the Collapse of the Wave Function

TL;DR

This paper reviews the fermionic projector approach to quantum theory, explores how it models entanglement and field interactions, and proposes a mechanism for wave function collapse during measurement.

Contribution

It introduces a novel collapse mechanism within the fermionic projector framework, addressing decoherence and the measurement problem.

Findings

Modeling of entanglement in the fermionic projector approach

Discussion of decoherence phenomena within the framework

Proposal of a wave function collapse mechanism

Abstract

After a brief introduction to the fermionic projector approach, we review how entanglement and second quantized bosonic and fermionic fields can be described in this framework. The constructions are discussed with regard to decoherence phenomena and the measurement problem. We propose a mechanism leading to the collapse of the wave function in the quantum mechanical measurement process.
