Physicists have developed a new approach in the search for a 'quantum spin liquid', a long sought state of quantum matter resembling a magnetic liquid whose quantum properties mean it never freezes.

The study of these fast-moving particles provides significant clues about the early universe.

In the literal sense, nothing is simpler than an elementary particle: By definition, a particle is considered to be elementary only if there is no evidence that it is made up of smaller constituents.
