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 ...

Graphene, a two-dimensional (2D) honeycomb sheet composed of carbon atoms, has attracted intense interests worldwide because of its outstanding properties and promising prospects in both basic and ...

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 ...
