Flux Periodicity Anomalies in Superconducting Loops as a Test of a Torsion-Based Geometric Model of Electromagnetism

This preprint proposes a concrete and falsifiable experimental test of a geometric model in which electromagnetic phase is interpreted as spacetime torsion (holonomy). The work predicts that a conventional s-wave superconducting loop with a controlled topological twist may exhibit a robust Φ₀/2 flux periodicity or systematic π-subharmonic features, while an otherwise identical planar control loop would not. A minimal experimental design, essential controls, and a clear discriminant against known mechanisms (such as Aharonov–Altshuler–Spivak oscillations or π-junction effects) are outlined. The proposal aims to provide a clean test of whether electromagnetic phase can depend on loop topology in a way not predicted by standard theory.
