Observation of a flat and extended surface state in a topological semimetal
Ryo Mori, Kefeng Wang, Takahiro Morimoto +3
A topological flatband, also known as drumhead states, is an ideal platform to drive new exotic topological quantum phases. Using angle-resolved photoemission spectroscopy experime…
Interlayer electronic transport in CaMnBi antiferromagnet
Aifeng Wang, D. Graf, Lijun Wu +4
We report interlayer electronic transport in CaMnBi single crystals. Quantum oscillations and angular magnetoresistance suggest coherent electronic conduction and valley pola…
Multiband effects and the possible Dirac states in LaAgSb
Kefeng Wang, C. Petrovic
Here we report the possible signature of Dirac fermions in the magnetoresistance, Hall resistivity and magnetothermopower of LaAgSb. The opposite sign between Hall resistivity…
Large linear magnetoresistance and magnetothermopower in layered SrZnSb
Kefeng Wang, C. Petrovic
We report the large linear magnetoresistance ( in 9 T field at 2 K) and magnetothermopower in layered SrZnSb crystal with quasi-two-dimensional Sb layers. A crossov…
Large magnetothermopower and Fermi surface reconstruction in SbTeSe
Kefeng Wang, D. Graf, C. Petrovic
We report the magnetoresistance, magnetothermopower and quantum oscillation study of SbTeSe single crystal. The in-plane transverse magnetoresistance exhibits a crossover a…
Quasi-two-dimensional Dirac fermions and quantum magnetoresistance in LaAgBi
Kefeng Wang, D. Graf, C. Petrovic
We report quasi-two-dimensional Dirac fermions and quantum magnetoresistance in LaAgBi. The band structure shows several narrow bands with nearly linear energy dispersion and D…
