Non--locality of particle spin: a consequence of interaction energy?

Abstract

Neutron interference measurements with macroscopic beam separation allow to study the influence of magnetic fields on spin properties. By calculating the interaction energy with a dynamic and deterministic model, we are able to establish that the phase shift on one component of the neutron beam is linear with magnetic intensity, and equally, that interaction energy as well as phase shifts do not depend on the orientation of the magnetic field. The theoretical treatment allows the conclusion that the non-local properties of particle spin derive from the classical equation for interaction energy and the fact, that interaction energy does not depend on magnetic field orientation. Additionally, it can be established that the 4 pi symmetry of spinors in this case depends on the scaling of magnetic fields.
