The Dirac Quantization Condition (DQC) for magnetic charges and its elegant Dirac-Wu-Yang (DWY) derivation based on U(1)em gauge theory predicts an electric / magnetic duality which to the best of our knowledge simply has never been observed in nature, as well as a charge quantization which is observed. The fact that this predicted duality has never been observed to our knowledge means as a matter of elementary logic that this DWY derivation (and the DQC itself) is either elegant but physically wrong, or elegant and correct but physically incomplete. This paper pinpoints a flawed assumption deeply-hidden in the DWY derivation that the south gauge field patch of the posited monopole charge differs from the north patch merely by an unobservable gauge-transformation. By correcting this assumption by defining an observable difference between the north and south patches, the DQC is made fully compatible with the non-observation of magnetic charges and its correct prediction of electric c...
Comment on “Massive electrodynamics and the magnetic monopoles”
Physical Review D, 2021
In this paper we correct previous work on magnetic charge plus a photon mass. We show that contrary to previous claims this system has a very simple, closed form solution which is the Dirac string potential multiplied by a exponential decaying part. Interesting features of this solution are discussed namely: (i) the Dirac string becomes a real feature of the solution; (ii) the breaking of gauge symmetry via the photon mass leads to a breaking of the rotational symmetry of the monopole's magnetic field; (iii) the Dirac quantization condition is potentially altered.
Dirac magnetic monopoles as goldstone and higgs bosons in the origin of mass
International Journal of Theoretical Physics, 1994
Inspired by the conjectures of Dirac (1931), theorists have regularly investigated the problem of the magnetic monopole. In the years since Dirac, it has been speculated by Schwinger (1969) and Chang (1972) that quarks consist of electric and magnetic charges. In non-...
Classical 4D Model of the Discrete Universe: Quantum and Relativity. 10. Magnetic Monopoles
In this chapter, we explore the hypothesis of magnetic monopoles, theoretical particles whose existence would explain the symmetry between electric and magnetic fields, first proposed by Dirac in 1931. Starting from the 4D Planck sphere, we relate the elementary electric charge e to a magnetic charge g, thus obtaining a derivation analogous to the Dirac equation. We analyze the ephemeral nature of the magnetic monopole, which manifests itself only for brief instants due to the rotation of the electron, which transforms the particle into a positron. This rotation ultimately generates the two poles of the magnetic field, suggesting that the electron and the positron are two manifestations of the same particle under different conditions. Finally, we discuss the current challenges to observe magnetic monopoles, due to the limitations of the measuring instruments that do not yet allow the detection of the effects of the 4D Planck sphere in such tiny times. With this, we leave open the possibility that future advances in experimental technology will reveal new evidence about this intriguing and fundamental symmetry in nature.
On the Dirac monopole mass scale
Revista Brasileira de Física, 1986
It i s shown, by a semi- classical argument, t hat the Dirac charge quantization i s still valid in the (classical) Born- lnfeld electromagnetic theory. Then it is possible to calculate Dirac's monopole mass in the framework of this theory, which is not possible in Maxwell's theory. The existence of an upper Iirnit for the field intensities in this theory plays an important role in this proof.

Dirac showed that the existence of one magnetic pole in the universe could offer an explanation of the discrete nature of the electric charge. Magnetic poles appear naturally in most Grand Unified Theories. Their discovery would be of greatest importance for particle physics and cosmology. The intense experimental search carried thus far has not met with success. I propose a Universe with magnetic poles which are not observed free because they hide in deeply bound monopoleanti-monopole states named monopolium. I study the feasibility of this proposal and establish signatures for confirming my scenario.

Building on his own previous research, Amherst College professor David S. Hall '91 and a team of international collaborators have experimentally identified a pointlike monopole in a quantum field for the first time. The discovery, announced this week, gives scientists further insight into the elusive monopole magnet, an elementary particle that researchers believe exists but have not yet seen in nature. [11] For the first time, physicists have achieved interference between two separate atoms: when sent towards the opposite sides of a semi-transparent mirror, the two atoms always emerge together. This type of experiment, which was carried out with photons around thirty years ago, had so far been impossible to perform with matter, due to the extreme difficulty of creating and manipulating pairs of indistinguishable atoms. [10] The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the relativistic quantum theory. The asymmetric sides are creating different frequencies of electromagnetic radiations being in the same intensity level and compensating each other. One of these compensating ratios is the electron-proton mass ratio. The lower energy side has no compensating intensity level, it is the dark energy and the corresponding matter is the dark matter.
