Medium Theory SMT Research №18 The Double-Slit Experiment as Dynamics of the Physical Medium Φ

Abstract In this work, the double-slit experiment is analyzed within the framework of Medium Theory SMT, where space-time is described as a nonlinear physical medium Φ. Instead of treating interference as a purely probabilistic quantum phenomenon, SMT interprets the observed pattern as the result of coherent phase dynamics and elastic deformations of the underlying medium. It is shown that propagating δΦ-perturbations naturally produce interference structures through phase coherence and nonlinear medium response, while localized particle-like configurations correspond to stable topological excitations of Φ. The emergence of the standard interference law follows directly from the medium dynamics without invoking wavefunction collapse or intrinsic randomness. The SMT description provides a unified physical mechanism for wave–particle duality, coherence loss, and pattern formation in the double-slit experiment, linking quantum behavior to deterministic field dynamics of the physical medium.
