Spin as a Position-Dependent Property on a Multi-Scale Guiding Wave: Second-Order Spinor Dynamics in a Realist Pilot-Wave Framework

This paper presents a realist pilot-wave framework exploring a possible physical inter-pretation of elementary particle spin. Rather than treating spin exclusively as an intrinsicnon-spatial degree of freedom, the model investigates the hypothesis that the measured spinstate emerges from the position of a localized excitation within a structured nonlinear spinor-valued guiding field W .A multi-scale substructure is considered, either through discrete spatial domains or con-tinuous high-frequency phase modulations. Both descriptions correspond to localized stablephase configurations in which the particle excitation may become dynamically trapped.A generalized guiding relation is proposed, combining an energy-flow contribution witha phenomenological spin-current contribution.Finally, the framework is formulated using a second-order complex Klein-Gordon-typespinor Lagrangian, leading to a conserved Noether current. The non-separable guiding con-figuration WAB is also discussed as a possible physical field representation of Bell-type cor-relations.
