论文摘要
WTE $ _2 $中的Magnetotransport研究研究了由于残留障碍而引起的Weyl节点之间的有限耦合。准粒子的各向异性散射是从经典和量子传输测量中证明的。开发了一种新的理论方法，以计算散射各向异性与疾病的相关长度的依赖性。理论与实验之间的比较首次揭示了wte $ _2 $（$ξ$ 〜nm）的短相关长度。该结果意味着Weyl节点和其他频段之间存在显着的耦合，因此节点间散射强烈降低了拓扑上的非平常性特性，例如手性异常。
The finite coupling between Weyl nodes due to residual disorder is investigated by magnetotransport studies in WTe$_2$. The anisotropic scattering of quasiparticles is evidenced from classical and quantum transport measurements. A new theoretical approach using a real band structure is developed to calculate the dependence of the scattering anisotropy with the correlation length of the disorder. A comparison between theory and experiments reveals for the first time a short correlation length in WTe$_2$ ($ξ$~nm). This result implies a significant coupling between Weyl nodes and other bands, so that inter-node scattering strongly reduces topologically non-trivial properties, such as the chiral anomaly.
