摘      要：Measuring the magneto-conductivity induced from impurities may help determine the impurity distribution and reveal the structure of a Weyl semimetal *** verify this,we utilize the Gaussian random disorder to simulate charged impurities in a two-node Weyl semimetal model and investigate the impact of charged impurities on magneto-conductivity in Weyl *** first compute the longitudinal magnetic conductivity and find that it is positive and increases proportionally with the parameter governing the Gaussian distribution of charged impurities,suggesting the presence of negative longitudinal *** we consider both the intra-valley and inter-valley scattering processes to calculate the induced transverse magneto-conductivity in the *** findings indicate that both inter-valley and intravalley scattering processes play important roles in the transverse *** locations of Weyl nodes can also be determined by magneto-conductivity *** is possible if the magnetic field strength and the density of charged impurities are ***,the measurement of magnetic conductivity may reveal the distribution of charged impurities in a given sample once the locations of the Weyl nodes have been *** findings can aid in detecting the structure of a Weyl semimetal sample,enhancing comprehension of magnetotransport in Weyl semimetals and promoting the development of valley electronics.
