Weyl goes chiral
(PHYSorg.com Physics)

Quasiparticles that behave like massless fermions, known as Weyl fermions, have been at the center of a string of exciting findings in condensed matter physics in recent years. The group of physicist Sebastian Huber at ETH Zurich now reports experiments in which they got a handle on one of the defining properties of Weyl fermions-their chirality.
