The Chiral Anomaly and Ultrahigh Mobility in Crystalline HfTe5
Huichao Wang, Chao-Kai Li, Haiwen Liu +11
HfTe5 is predicted to be a promising platform for studying topological phases. Here through an electrical transport study, we present the first observation of chiral anomaly and ul…
Positive Magneto-conductivity of Weyl Semimetals in the Ultra-quantum Limit
Chui-Zhen Chen, Haiwen Liu, Hua Jiang +1
In this paper, we numerically study the magnetic transport properties of disordered Weyl semimetals (WSM) in the ultra-quantum limit. We find a positive magnetic conductivity for t…
Magnetic tunneling induced Weyl node annihilation in TaP
Cheng-Long Zhang, Su-Yang Xu, C. M. Wang +20
Weyl nodes are topological objects in three-dimensional metals. Their topological property can be revealed by studying the high-field transport properties of a Weyl semimetal. Whil…
Giant negative magnetoresistance induced by the chiral anomaly in individual Cd3As2 nanowires
Cai-Zhen Li, Li-Xian Wang, Haiwen Liu +3
Cd3As2 is a newly booming Dirac semimetal with linear dispersion along all three momentum directions and can be viewed as 3D analog of graphene. As breaking of either time reversal…
Tunable Anderson metal-insulator transition in quantum-spin Hall insulators
Chui-Zhen Chen, Haiwen Liu, Hua Jiang +3
We numerically study disorder effects in Bernevig-Hughes-Zhang (BHZ) model, and find that Anderson transition of quantum spin-Hall insulator (QSHI) is determined by model parameter…
Building topological device through emerging robust helical surface states
Zibo Wang, Juntao Song, Haiwen Liu +2
We propose a nonlocal manipulation method to build topological devices through emerging robust helical surface states in Z_2=0 topological systems. Specifically, in a ribbon of Z_2…
