Determination of the spin orientation of helical electrons in monolayer WTe2
Cheng Tan, Ming-Xun Deng, Feixiang Xiang +7
Monolayer WTe2 is predicted to be a quantum spin Hall insulator (QSHI) and electron transport along its edges has been experimentally observed. However, the 'smoking gun' of QSHI,…
The prolonged decay of RKKY interactions by interplay of relativistic and non-relativistic electrons in semi-Dirac semimetals
Hou-Jian Duan, Yan-Yan Yang, Shi-Han Zheng +4
The Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction has been extensively explored in isotropic Dirac systems with linear dispersion, which typically follows an exponent decaying r…
Electrically tunable Kondo effect as a direct measurement of the chiral anomaly in disorder Weyl semimetals
Yan-Yan Yang, Ming-Xun Deng, Hou-Jian Duan +2
We propose a mechanism to directly measure the chiral anomaly in disorder Weyl semimetals (WSMs) by the Kondo effect. We find that in a magnetic and electric field driven WSM, the…
