The dynamical conductivity in metallic carbon nanotubes with impurities is studied based on an exact numerical diagonalization. The results show clearly that the conductivity deviates considerably from the usual Drude behavior due to the absence of backward scattering and the presence of a perfect conducting channel in the low‐frequency region.
