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 ...

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 ...

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 ...

Researchers from the Helmholtz-Zentrum Berlin für Materialien und Energie have, in cooperation with colleagues from Dresden, St. Andrews, La Plata and Oxford, for the first time observed magnetic ...

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 ...

If you break a magnet in two, you don't get a north half and a south half - you get two new magnets, each with two poles. "Monopoles" were famously predicted to exist, external by physicist Paul Dirac ...
