Abstract

We calculate the magnetoconductivity of the Weyl semimetal with ℤ2 topological charge and chiral anomaly utilizing the recently developed hydrodynamic theory. The system in question will be influenced by magnetic fields connected with ordinary Maxwell and the second U(1)-gauge field, which couples to the anomalous topological charge. The presence of chiral anomaly and ℤ2 topological charge endow the system with new transport coefficients. We start with the linear perturbations of the hydrodynamic equations and calculate the magnetoconductivity of this system. The holographic approach in the probe limit is implemented to obtain the explicit dependence of the longitudinal magneto-conductivities on the magnetic fields.
