Unusual interlayer quantum transport behavior caused by the zeroth Landau level in YbMnBi2
J. Y. Liu, J. Hu, D. Graf +10
Relativistic fermions in topological quantum materials are characterized by linear energy-momentum dispersion near band crossing points. Under magnetic field, relativistic fermions…
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…
Topological nodal-line fermions in ZrSiSe and ZrSiTe
Jin Hu, Zhijie Tang, Jinyu Liu +8
The discovery of topological semimetal phase in three-dimensional (3D) systems is a new breakthrough in topological material research. Dirac nodal-line semimetal is one of the thre…
Electron-hole asymmetry, Dirac fermions, and quantum magnetoresistance in BaMnBi2
Lijun Li, Kefeng Wang, D. Graf +3
We report two-dimensional quantum transport and Dirac fermions in BaMnBi2 single crystals. BaMnBi2 is a layered bad metal with highly anisotropic conductivity and magnetic order be…
