Poynting’s Theorem with Magnetic Monopoles
where c = 1/ √ 0μ0 is the speed of light in vacuum. In macroscopic electrodynamics we consider media that contain volume densities of electricand Ampèrian magnetic-dipole moments,Pe andMe, respectively (often called the densities of polarization and magnetization). Supposing that magnetic charges exists, the media could also contain volume densities of (Gilbertian) electricand magnetic-dipole m...
متن کاملMinicharges and Magnetic Monopoles
Minicharged particles arise naturally in extensions of the Standard Model with a kinetic mixing term between the ordinary electromagnetic U(1) and an extra “hidden sector” U(1). In this note we study the compatibility of these particles with the existence of magnetic monopoles. We find that angular momentum quantization allows only certain combinations of ordinary and hidden monopole charge. Us...
متن کاملDifficulties with Photonic Searches for Magnetic Monopoles
Recently, there have been proposals that the classic Euler-Heisenberg Lagrangian together with duality could be employed to set limits on magnetic monopoles having masses less than 1 TeV. The D0 collaboration at Fermilab has used such a proposal to set mass limits based on the nonobservation of pairs of photons each with high transverse momentum. In this note, we critique the underlying theory,...
متن کاملAre magnetic monopoles hadrons?
The charges of magnetic monopoles are constrained to a multiple of times the inverse of the elementary unit electric charge. In the standard model, quarks have fractional charge, raising the question of whether the basic magnetic monople unit is a multiple of or three times that. A simple lattice construction shows how a magnetic monopole of the lower strength is possible if it interacts with g...
متن کاملEmergent magnetic monopoles in frustrated magnetic systems.
This Theme Issue reports papers presented at a Discussion Meeting intended to bring together theorists and experimentalists working on magnetic charge carriers, or monopoles, in both natural and artificially nanostructured spin ice lattices, and to explore related topics on Berry phase physics and domain wall motion and a possible solid-state/cosmology interface in these systems. The Discussion...
