abstract

There have been many searches for magnetic monopoles in flight, but few for monopoles in matter. We have searched for magnetic monopoles in meteorites, schists, ferromanganese nodules, iron ores and other materials. The detector was a superconducting induction coil connected to a SQUID (Superconducting Quantum Interference Device) with a room temperature bore 15 cm in diameter. We tested a total of more than 331 kg of material including 112 kg of meteorites. We found no monopole and conclude the overall monopole/nucleon ratio in the samples is $<1.2 \times 10^{-29}$ with a 90\% confidence level.

  1. The Euler-Heisenberg action for a $U(1)\times U(1)$ dyon quantum electrodynamics

    hep-th 2026-07 accept novelty 6.5 of 10

    One-loop Euler-Heisenberg Lagrangian for U(1)×U(1) dyon QED produces hybrid refractive indices and vacuum birefringence that reduce exactly to ordinary QED when magnetic charge vanishes.
