DYON SPIN AND STATISTICS - FIBER-BUNDLE THEORY OF INTERACTING MAGNETIC AND ELECTRIC CHARGES

The quantum mechanics of a system of nonrelativistic electrically and magnetically charged particles is formulated by introducing as the classical configuration space a certain U(1) bundle over the set of physical particle configurations. In this way one obtains a well-defined and single-valued classical action; and in the corresponding quantum theory, the origin of half-integral spin and of asymptotic Fermi-Dirac statistics in the description of composite systems of bosons finds its expression in terms of the bundle's structure. © 1979 The American Physical Society.
