In a recent article entitled "Real-space imaging and control of chiral anomaly induced current at room temperature in topological Dirac semimetal" published in the journal Science Advances B.C. Park et al. from the Sungkyunkwan University and collaborating partners have reported a world-first success in resolving the spatio-temporal motion of chiral fermions with a direct measurement.  

Chiral fermions are expected to play a key role in the development of future quantum devices. Now using a TeraCube M2 Terahertz near-field scanning system real-space imaging and also the control of chiral anomaly induced currents on the topological Dirac semimetal KZnBi has been demonstrated at room temperature on a ps time- and µm length-scale. The results of this study are bringing topological Dirac semimetals a big step closer to their use in information technology.
