Within the context of the nonrelativistic theory of dyons, we study a number of interrelated issues concerning the quantum formulation of magnetic charge. We begin by solving the two‐body Schrodinger equation for an arbitrarily oriented singularity line (string) in terms of the known solutions with the string on the z axis. Charge quantization conditions emerge by requiring that the wavefunctions be single valued. The general solutions express the necessary gauge covariance of the wavefunctions… 

Hidden symmetries, spin and charge of artificial magnetic monopoles

We discuss the non-Abelian artificial magnetic monopoles associated with n -level energy crossing in quantum systems. We found that hidden symmetries reveal themselves as observables such as spin,

Theoretical and experimental status of magnetic monopoles

The Tevatron has inspired new interest in the subject of magnetic monopoles. First there was the 1998 D0 limit on the virtual production of monopoles, based on the theory of Ginzburg and




The scattering of an electric charge from a magnetic monopole is discussed in a way which explicitly incorporates conservation of angular momentum. The Dirac quantization condition for the physical

Dirac monopole theory with and without strings

It is shown that in Dirac's formulation of the quantum-mechanical interaction of a magnetic monopole and an electric charge the singular string he attached to the monopole can be moved arbitrarily by

Scattering on magnetic charge

The nature of magnetic monopoles in an SO(3) gauge theory is explored by examining how they scatter charged particles. Peripheral scattering, where the momentum transfer is much less than the mass of

Avoiding ''Dirac's veto'' in monopole theory

Using ideas introduced by Wu and Yang in their recent nonsingular formulation of an action principle for classical Dirac magnetic monopoles, we modify Dirac's original formulation of the problem so

Magnetic charge and the charge quantization condition

Two viewpoints concerning magnetic charge are distinguished: that of Dirac, which is unsymmetrical, and the symmetrical one, which embodies invariance under charge rotation. It is pointed out that
