An Accumulative Model for Quantum Theories

TL;DR

This paper introduces a novel accumulative stochastic model for quantum theories based on path integrals, which reproduces quantum predictions while being non-local and non-causal in spacetime but local in path space.

Contribution

It presents a new mathematical universe model as an accumulative stochastic process compatible with quantum theories, offering a different perspective on locality and causality.

Findings

Model reproduces quantum predictions accurately

Simulations verify the model's validity

Discusses potential experimental discrepancies

Abstract

For a general quantum theory that is describable by a path integral formalism, we construct a mathematical model of the universe as a sample point of an accumulative stochastic process. The model give predictions that are nearly identical to the given quantum theory. The model is neither local nor causal in spacetime, but is both local and causal is in a non-observable path space. The probabilistic nature of the squared wavefunction is a natural consequence of the model. We verify the model with simulations, and we discuss possible discrepancies from conventional quantum theory that might be detectable via experiment. Finally, we briefly discuss the physical implications of the model.
