Massless particle discovery could radically accelerate electronics

•, By Colin Jeffrey

 Scientists believe that this new particle may result in super-fast electronics and significant inroads into novel areas of quantum computing.

There are two types of particles that make up the universe and everything in it: fermions and bosons. In simple terms, fermions are all the particles that make up matter (for example, electrons), and bosons are all the particles that carry force (for example, photons). Ordinarily, fermions such as electrons can collide with each other, losing energy, and no two fermions can share the same state at the same position at the same time. Weyl fermions being massless, however, have no such restrictions.

Weyl fermions were first mooted in 1929 by physicist and mathematician Hermann Weyl, who theorized that massless fermions able to carry an electric charge could exist. Without mass, he believed, electrons created from Weyl fermions would be able to move electric charge in a circuit much more quickly than ordinary electrons. In fact, according to this latest research, electric current carried by Weyl electrons in a test medium is able to move at least twice as fast as that carried by electrons in graphene and at least 1,000 times faster than in ordinary semiconductors.
