A New Paradigm for Single-Particle Double-Slit Interference: Cavity-Induced Nonlocal Quantized Momentum Transfer with no Need for Schrödinger’s Wavefunction, Self-Interference, and Wavefunction Collapse

We propose a quantum framework where cavity-induced nonlocal stochastic quantized momentum transfer governs double-slit interference of single eelectrons, replacing self-interference, wavefunction collapse, and Schrödinger’s wavefunction description. Using Heisenberg’s operator formalism, we model the electron’s interaction with the double slit as a quantized field potential. This approach explains interference via discrete momentum transfer through stochastic cavity modes. We explore its role as a non-local hidden-variable mechanism, predicting deviations in Bell violation, and finer discrete interference fringes in short cavity-mode wavelength regimes, opening new avenues for experimental verification. Our new interpretation of quantum dynamics sheds light on long-standing debates about quantum reality, hidden variables, wave-function superposition and Schrödinger’s cat, the illusion of self-interference of a single electron, and instantaneous wavefunction collapse misconception in the measurements. Our theory possesses the deterministic description of an electron a stochastic yet nonlocal hidden variable characteristic of the quantized cavity modes. It meets Einstein’s desire for a more complete theory and bridges the gap between physical reality and the incomplete conventional quantum theory that requires confusing Copenhagen or many-world interpretations.
