Abstract
We compute the electric conductivity of quark matter at finite temperature and a quark chemical potential under a magnetic field beyond the lowest Landau level approximation. The electric conductivity transverse to is dominated by the Hall conductivity . For the longitudinal conductivity , we need to solve kinetic equations. Then, we numerically find that has only a mild dependence on and the quark mass . Moreover, first decreases and then linearly increases as a function of , leading to an intermediate region that looks consistent with the experimental signature for the chiral magnetic effect. We also point out that at a nonzero remains within the range of the lattice-QCD estimate at .
