Nearly massless Dirac fermions hosted by Sb square net in BaMnSb2
Jinyu Liu, Jin Hu, Huibo Cao +8
Layered compounds AMnBi2 (A=Ca, Sr, Ba, or rare earth element) have been established as Dirac materials. Dirac electrons generated by the two-dimensional (2D) Bi square net in thes…

Pi Berry phase and Zeeman splitting of TaP probed by high field magnetotransport measurements
J. Hu, J. Y. Liu, D. Graf +8
The chiral anomaly-induced negative magnetoresistance and non-trivial Berry phase are two fundamental transport properties associated with the topological properties of Weyl fermio…

A magnetic topological semimetal Sr1-yMn1-zSb2 (y, z< 0.1)
J. Y. Liu, J. Hu, Q. Zhang +14
Weyl (WSMs) evolve from Dirac semimetals in the presence of broken time-reversal symmetry (TRS) or space-inversion symmetry. The WSM phases in TaAs-class materials and photonic cry…
