A functional model of interactions in quantum theory

Abstract

In this paper, a functional model of interactions in quantum theory (QT) is proposed. A functional model describes the dynamic evolution of a physical system in terms of process steps and intermediate states. That is, it describes how things function. The proposed functional model of QT interactions was developed in the context of the author's work toward a computer model of QT with the goal of supporting the largest possible scope of QT concepts. In QT, the results of interactions are computed using quantum field theory (QFT). Therefore, the proposed functional model of interactions is based on QFT. There are a number of important QT concepts, such as measurement, entanglement, and decoherence, that are related to interactions. The functional model of interactions also addresses these phenomena.
