The Photon Soul Theorem: A Cohomological Approach to Interference Visibility

This experimental work introduces the "photon soul effect," demonstrating that topological obstructions in a photon’s field structure can lead to reduced interference contrast. It models single-photon quantum field amplitudes as a sheaf on an étale site and identifies an obstruction class whose nontriviality causes a measurable drop in interferometric visibility.
