简介:	(3:30~4:00pm, Tea, Coffee, and Cookie) Recent observation of the Fermi arc surface states in the non-central-symmetric tantalum monoarsenide in ARPES measurements indicates the existence of the topological Weyl semimetals. In this talk, I will show our results of the electric transport measurements on TaAs and several other possible Weyl semimetals. Our studies show that TaAs is a compensated semimetal with extremely low carrier concentrations and ultrahigh mobility. The Strong SdH oscillations and large, linear magnetoresistance in TaAs indicate a strong backscattering protection in these Weyl semimetals. I will also discuss the negative longitudinal magnetoresistance which is possibly caused by the well-known ABJ anomaly.
