New result in hunt for mysterious magnetic monopoles

Cutting a magnet in half yields two magnets, each with its own north and south pole. This apparent absence of an isolated magnetic pole, or "magnetic monopole," has puzzled physicists for more than a century. It would seem ...

Physicists propose perfect material for lasers

Weyl semimetals are a recently discovered class of materials in which charge carriers behave the way electrons and positrons do in particle accelerators. Researchers from the Moscow Institute of Physics and Technology and ...

Researchers turn liquid metal into a plasma

Most laypersons are familiar with the three states of matter as solids, liquids, and gases. But there are other forms that exist. Plasmas, for example, are the most abundant form of matter in the universe, found throughout ...

Weyl points: Long-sought phenomenon finally detected

Part of a 1929 prediction by physicist Hermann Weyl—of a kind of massless particle that features a singular point in its energy spectrum called the "Weyl point,"—has finally been confirmed by direct observation for the ...

Artificial magnetic monopoles discovered

A team of researchers from Cologne, Munich and Dresden have managed to create artificial magnetic monopoles. To do this, the scientists merged tiny magnetic whirls, so-called skyrmions. At the point of merging, the physicists ...
