Formulations of magnetic monopoles in a Hilbert-space formulation of quantum mechanics require Dirac's quantization condition of magnetic charge, which implies a large value that can easily be ruled out for elementary particles by standard atomic spectroscopy. However, an algebraic formulation of non-associative quantum mechanics is mathematically consistent with fractional magnetic charges of small values. Here, spectral properties in non-associative quantum mechanics are derived, applied to the ground state of hydrogen with a magnetically charged nucleus. The resulting energy leads to new strong upper bounds for the magnetic charge of various elementary particles that can appear as the nucleus of hydrogen-like atoms, such as the muon or the antiproton.

O ct 2 01 8 Small magnetic charges and monopoles in non-associative quantum mechanics
2018
Weak magnetic monopoles with a continuum of charges less than the minimum implied by Dirac’s quantization condition may be possible in non-associative quantum mechanics. If a weakly magnetically charged proton in a hydrogen atom perturbs the standard energy spectrum only slightly, magnetic charges could have escaped detection. Testing this hypothesis requires entirely new methods to compute energy spectra in non-associative quantum mechanics. Such methods are presented here, and evaluated for upper bounds on the magnetic charge of elementary particles.

Strange Magnetism and the Anapole Structure of the Proton
Science, 2000
The violation of mirror symmetry in the weak force provides a powerful tool to study the internal structure of the proton. Experimental results have been obtained that address the role of strange quarks in generating nuclear magnetism. The measurement reported here provides an unambiguous constraint on strange quark contributions to the proton's magnetic moment through the electron-proton weak interaction. We also report evidence for the existence of a parity-violating electromagnetic effect known as the anapole moment of the proton. The proton's anapole moment is not yet well understood theoretically, but it could have important implications for precision weak interaction studies in atomic systems such as cesium.
Magnetic monopoles and dyons revisited: A useful contribution to the study of classical mechanics
Graduate level physics curricula in many countries around the world, as well as senior-level undergraduate ones in some major institutions, include Classical Mechanics courses, mostly based on Goldstein's textbook masterpiece. During the discussion of central force motion, however, the Kepler problem is virtually the only serious application presented. In this paper, we present another problem that is also soluble, namely the interaction of Schwinger's dual-charged (dyon) particles. While the electromagnetic interaction of magnetic monopoles and electric charges was studied in detail some 40 years ago, we consider that a pedagogical discussion of it from an essentially classical mechanics point of view is a useful contribution for students. Following a path that generalizes Kepler's problem and Rutherford scattering, we show that they exhibit remarkable properties such as stable non-planar orbits, as well as rainbow and glory scattering, which are not present in the ordinary scattering of two singly charged particles. Moreover, it can be extended further to the relativistic case and to a semi-classical quantization, which can also be included in the class discussion.
ON THE PROTON AND ELECTRON CHARGES
This article presents a geometric kinematic approach to demonstrate the existence of the proton charge as a consequence of the rotation of a 4 dimensional framework of the universe and the existence of the electron and its charge as a consequence of proton creation. In this article, the author presents the existence of the proton and electron charges as the endpoints of a vortex charge tunnel that passes through the interior dimension of the 4-Ball universe connecting two points in our 3 dimensional surface volume. *Note: Reference [10] target URL has been hijacked subsequent to this article's posting...

Constraints on monopole-dipole potential from the tests of gravity
arXiv (Cornell University), 2023
Ultralight Axion Like Particle (ALP) can mediate a long range monopole-dipole macroscopic force between Earth and Sun if Earth is treated as a polarized source. There are about 10 42 number of polarized electrons in Earth due to the presence of the geomagnetic field. The monopole-dipole interactions between electrons in Earth and nucleons in Sun can influence the perihelion precession of Earth, gravitational light bending and Shapiro time delay. The contribution of monopole-dipole potential is limited to be no larger than the measurement uncertainty. We obtain the first bound on monopole-dipole strength from single astrophysical observations. The perihelion precession of Earth puts the stronger bound on monopole-dipole coupling strength as g S g P 1.75 × 10 −16 for the ALP of mass m a 1.35 × 10 −18 eV. We also obtain constraints on monopole-dipole coupling strength as g S g P 5.61×10 −38 from two different astrophysical observations such as the perihelion precession of the planet and the red giant branch. The bound is three orders of magnitude stronger than the Eot-Wash experiment and one order of magnitude stronger than the (Lab) N S × (Astro) e P limit.

Magnetic monopoles have been a subject of interest since Dirac established the relation between the existence of a monopole and charge quantization. 't Hooft and Polyakov proved that they can arise from gauge theories as the result of a non trivial topology. In their scheme the mass of the monopole turns out to be large proportional to the vector meson mass arising from the spontaneous breaking of the symmetry at unification scales. To reduce from the GUT scale to the Standard Model scale we modify the potential in line with Coleman-Weinberg schemes and generate a second deeper minimum turning the original vacuum quantum mechanically unstable. This mechanism leads to radiating monopoles of lower mass which could be detected at LHC.
