The theory of Relativistic Schrodinger Equations offers a local-realis
tic interpretation for the Bohm-Aharonov effect. The wave function psi
(x) is built up by a (scalar) localization field l(x) and a kinetic (v
ector) field k(mu) (x), which extends far beyond the support of l(x) a
nd thus transfers electromagnetic effects from far away to the locatio
n of the wave packet.
