Macroscopic Quantum Tunneling, Josephson Physics, and the Asymmetric Source Field Model (ASFM)

This work presents a unified theoretical framework linking macroscopic quantum tunneling, Josephson physics, and the fundamental quantum field structure of matter within the Asymmetric Source Field Model (ASFM).
The ASFM describes matter as an interference phenomenon between two coherent, phase-shifted source fields — a constructive “material” component and its conjugate “antimatter” counterpart. Their residual superposition forms stable interference nodes, defining the structure of atoms, nuclei, and macroscopic quantum systems.

By deriving the Josephson energy relation from the ASFM interference term, the paper demonstrates that both microscopic and macroscopic coherence phenomena share a common mathematical and physical origin.
The approach reproduces the Josephson coupling form E(Δθ) = E₀ − K cos(Δθ) and extends it to a fractal, scale-invariant field model applicable from nuclear stability to superconducting condensates.

The study also predicts measurable deviations — including non-sinusoidal current–phase relations and asymmetric Shapiro ladders — providing potential experimental tests of the ASFM framework.
This work builds on the author’s previous publication “Fractal Interference Nodes as the Origin of Nuclear Fission Products” (Physics Essays, 2025, DOI 10.5281/zenodo.15209035) and establishes the conceptual foundation for a forthcoming detailed exposition of the model.
