Experimental observation of Weyl fermions in a tantalum arsenide crystal ends search after 86 years
Two international teams claim to have found the basic building block of the electron, the Weyl fermion, which was first theorised 86 years ago. The discovery of this new quasiparticle was not made in a particle collider, however, but inside a synthetic crystal. The fermion, which is massless, could potentially give rise to super-fast electronics and photonics, the discoverers claim.
