Magnetic monopoles have been predicted to occur as emergent fractional quasiparticles inside pyrochlore spin ice, a frustrated magnetic insulator. Experimental signatures of such emergent monopoles ...

(PhysOrg.com) -- For decades, scientists have been intrigued by the hypothetical existence of magnetic monopoles - particles with only a north or south magnetic pole, thus having a nonzero magnetic ...

(PhysOrg.com) -- Scientists have captured the first direct images of magnetic monopoles which were theoretically conceived by the British-Swiss physicist Dirac in the early 1930s who showed that their ...

For decades, researchers have been searching for magnetic monopoles -- isolated magnetic charges, which can move around freely in the same way as electrical charges. Magnetic poles normally only occur ...

Electric charges can exist in isolation, and positive protons and negative electrons are capable of independent action. Magnets, on the other hand, always seem to come in pairs of north and south ...

Ever since magnetic monopoles were first predicted by Paul Dirac in 1931, physicists have looked in vain for these elusive entities in everything from particle accelerators to Moon rocks. Now, two ...

The collective excitation modes of hedgehog lattices are governed by oscillation of Dirac strings, connecting a hedgehog and an antihedgehog, which can be used to study their spatial configuration in ...

Faraday and Dirac constructed magnetic monopoles using the practical and mathematical tools available to them. Now physicists have engineered effective monopoles by combining modern optics with ...
