Topological Dirac and Weyl semimetals are currently attracting intense interest due to their exotic physical properties. Transition metal diarsenides such as MoAs_{2} and WAs_{2} have been reported to harbor very high magnetoresistance suggesting the possible existence of a topological quantum state. although this conclusion remains dubious.
