Abstract

A statistical simulation is presented which reproduces the correlation obtained from EPR coincidence experiments without non-local connectivity. We suggest that spin carries two complementary properties. In addition to the spin polarization, we identify spin coherence. This spin attribute is anti-symmetric and generates the helicity. In addition this spin has structure formed from two orthogonal magnetic moments. From these, a resonance spin results from their coupling in free flight. Upon encountering a filter, the resonance spin 1 decouples back into two independent spins of $\frac{1}{2}$, with one aligning with the filter and the other randomizing. The process of decoupling the resonance spin is responsible for the quantum correlation which results in the observe violation of Bell's Inequalities. The polarized states give a CHSH value of 2 while the resonance spin give a CHSH value of 1. Coherence can only be formulated by the existence of a bivector which gives a spin the same geometric structure as a photon. Although this work is not about Bell's theorem, we note that there are no hidden variables (HV). The only local variable is the angle that orients a spin on the Bloch sphere, first identified in the 1920's. The new features introduced are changing the spin symmetry from SU(2) to the quaternion group, $Q_8$, and the introduction of a bivector into spin which leads to an element of reality which is anti-Hermitian. The calculations use standard spin algebra, and properties of quaternions.

The commenter has declared there is no conflict of interests.
Comment: According to formula (32) and some other remarks in the paper, the correlation which is predicted by this model is actually a 75:25 mixture of the famous saw-tooth or triangular wave, and the "French mustache" curve, which the author associates with polarization and coherence respectively. Neither curve violates Bell-CHSH inequalities so their mixture does not either, and hence cannot be anywhere near the negative cosine predicted by the conventional QM EPR-B model. The author writes that his work has nothing to do with Bell's theorem but actually it has everything to do with that theorem, since his two "submodels" (polarization, coherence) are local hidden variable models in Bell's mathematical sense of that phrase. NB. "hidden" means, hidden with respect to conventional QM; "local" means that the measurement functions only depend on the local setting.
