  We continue our analysis on conductivity in the anisotropic background by
employing the D-brane probe technique, where the D-branes play the role of
charge carriers. The DC and AC conductivity for massless charge carriers are
obtained analytically, while interesting curves for the AC conductivity are
also plotted. For massive charge carriers, we calculate the DC and AC
conductivities in the dilute limit and we fix the parameters in the
Einstein-Maxwell-dilaton theory so that the background exhibits the same
scaling behaviors as those for real-world strange metals. The DC conductivity
at finite density is also computed.
